Abstract

This book describes novel synthetic methodologies for two kinds of structurally elaborate metal complexes: a heterometallic complex and a tetrahedral chiral-at-metal complex. The book provides the tools and inspiration to chemists for development of metal complexes with wide structural diversity than had previously been possible. For each of the two topics, existing synthetic methods for similar compounds are discussed first, and then new strategies are presented, followed by the demonstration of the synthesis of novel compounds supported by experimental results. Both of the final products in this research, a Co-Ni heterometallic complex covered in the first topic and a tetrahedral chiral-at-metal complex in the second one are difficult to obtain by using common synthetic methods for thermodynamic reasons. This research achieved highly selective syntheses of these compounds using newly designed strategies that enable precise kinetic control. Such an approach will be useful for synthesizing other new metal complexes. Since the last century, organic chemistry has flourished with the development of a variety of synthetic techniques that make precise kinetic control possible. Coordination chemistry of 3d or main-group transition metals has been mainly based on simple one-step reactions that yield only thermodynamic products. The publication of this book helps pave the way to kinetically controlled precise syntheses of various metal complexes.

Abstract

This book presents several helpful synthetic methods for diverse multinuclear complexes. The results described can be used to selectively connect mononuclear as well as multinuclear complexes with other metal complexes to construct valuable photofunctional compounds. Using the new synthetic methods, it was possible to selectively connect several types of metal complexes in a single step under relatively mild reaction conditions. This so-called building block approach utilizes various C-C coupling reactions between metal complexes with functional groups as active moieties. Owing to the large pi-conjugation systems, the multinuclear complexes synthesized using coupling reactions showed a strong absorption ability over a wide range of visible light and long emission lifetimes, which are ideal properties for photosensitizers and light absorbers. By combining these coupling methods with the newly developed hydrogenation reactions, the binding mode of the linkers in multinuclear complexes can be modified in order to tune the photophysical properties and photocatalytic ability. As such, the synthesized multinuclear complexes can be used for various purposes, e.g., as photocatalysts and photosensitizers, and in light-harvesting systems. The synthetic methods and strategies presented in this book diversify not only the structures but also functions of multinuclear complexes.

Abstract

This volume reviews recent developments in the ?elds of organometallic and coordination chemistry of the actinides, and in particular uranium. Actinide chemistryingeneralhasrecentlybeenrejuvenatedwithdemonstrationsof- precedented structures, reactivity, and physical properties. While organou- nium chemistry can be traced back to the Manhattan Project, most of these efforts were unsuccessful. However, by the mid-1950s the ?rst uranium - clopentadienyl (Cp) complexes were being reported, e. g. tricyclopentadienyl uranium(IV) chloride, (C H ) UCl. The late1960s heralded thesynthesis and 5 5 3 structural elucidation of uranocene,  bis(cyclooctatetraenyl)uranium(IV), U(C H ) , an expanded-ring sandwich compound that provided tantalizing 8 8 2 evidence that 5f orbitals might be involved in bonding. One of the chapters in this volume details the expansion of this kind of work to include mixed sandwich U(III) cyclooctatetraene and pentalene complexes. As discussed by several of the authors, the availability of easily prepared mid-valent sta- ing materials has been one of the primary factors involved in reinvigorating this ?eld. Of particular interest to many readers will be the binding of small molecules by both organometallic and coordination compounds of uranium. Some of the holy grails of this chemistry include the activation of dinitrogen, carbon monoxide, and carbon dioxide. Various aspects of this work can be foundinallthreechapters,butaredetailedinparticularbyO. T. Summerscales andF. G. N. Cloke. The origins of coordination compounds of uranium are dif?cult to de?ne precisely because thede?nition of what constitutes acoordination compound versus apurelyinorganiccompoundcanbedif?culttodifferentiate. However, the coordination chemistry of uranium is very old, dating back to at least the early1800s.

Abstract

TheprototypicalcatalyticreductiveC-Cbondformations,theFischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homo- neous metal catalysis, accounting for the production of over 7 million metric tons of aldehyde annually. Despite the impact of these prototypical reductive C-C bond formations, this ?eld of research lay fallow for several decades. Eventually, the increased availability of mild terminal reductants, in part- ular silanes, led to a renaissance in the area of catalytic reductive C-C bond formation.Forexample,the?rstcatalyticreductiveC-Ccouplingsbeyond- droformylation, which involve the hydrosilylative dimerization of conjugated dienes [6-12], appeared in 1969 - approximately 16 years after the ?rst - ported metal-catalyzed alkene hydrosilylation [13]. Following these seminal studies, the ?eld of catalytic reductive C-C bond formation underwent exp- sivegrowth,culminatingintheemergenceofanevergrowingbodyofresearch encompassing a powerful set of transformations. To our knowledge, no thematic volumes devoted solely to metal-catalyzed reductive C-C bond formationhave been assembled. For the ?rst time, in this issue of Topics in Current Chemistry,wepresent acompilation ofmonographs from several leaders in this burgeoning area of research. This collection of reviews serves to capture the diversity of catalytic reductive C-C couplings presently available and, in turn, the remarkable range of reactivity embodied by such transformations. There is no indication that this ?eld has reached its zenithanditisthehopeofthepresentauthorthatthisvolumewillfuelfurther progress.

Abstract

Computational methods have become an indispensible tool for elucidating the mechanism of organometallic reactions. This snapshot of state-of-the-art computational studies provides an overview of the vast field of computational organometallic chemistry. Authors from Asia, Europe and the US have been selected to contribute a chapter on their specialist areas. Topics addressed include: DFT studies on zirconium-mediated reactions, force field methods in organometallic chemistry, hydrogenation of π-systems, oxidative functionalization of unactivated C-H bonds and olefins, the osmylation reaction, and cobalt carbonyl clusters. The breadth and depth of the contributions demonstrate not only the crucial role that computational methods play in the study of a wide range of organometallic reactions, but also attest the robust health of the field, which continues to benefit from, as well as inspire novel experimental studies.
