Book Description
Coordination compounds involving metal-nitrogen bonds are a well-developed class of organometallic chemistry. In contrast, the chemistry of the heavier analogues of nitrogen, e.g. phosphorus and arsenic is far less explored. This thesis describes the synthesis and characterization of suitable rhenium and osmium PNP pincer compounds to serve as starting materials for further conversion towards heavy transition metal pnicogen complexes. A square-planar Os(II) PNP pincer complex is reported which features a unique electronic structure and serves as a convenient starting material to synthesize ...

Book Description
The role of bulky tin ligands in the stabilization of transition metal complexes with electronic unsaturation has been studied to understand the mode of binding of small molecules at an unsaturated metal center. We were able to isolate electronically unsaturated Pt-Sn bimetallic complexes effective in the reversible activation of small molecules including CO, H2, C2H4, and NH3 at room temperature. We have examined the effect of the modification of ligands in Pt-Sn bimetallic complexes for the activation of small molecules and have observed that the Pt(SnBut3)2(CNBut)2 bimetallic complex reversibly activates hydrogen at room temperature both in the solid state and in solution. Similarly, we have also prepared bimetallic Pt-Sn complexes with an NHC carbine ligand which were also shown to activate hydrogen and alkenes reversibly. A bimetallic Fe-Sn cluster complex, Fe2 ([mu]-SnBut2)2(CO)8, was synthesized from the reaction of But3SnH with the Fe2(CO)9 and shown to be selective at activating the benzylic C-H bond of alkylaromatic solvent molecules. The new complexes containing tin have been characterized spectroscopically to gain an insight into the reaction mechanism involved in small molecule activation.

Book Description
A text for use in a one-semester course for upper-level students familiar with basic organic chemistry, or as a survey course for practicing organic chemists. Chapters 1 and 2 present a brief overview of the formalisms and mechanisms required to understand the processes discussed in chapters 3-10, which deal with the application of transition metal organometallic chemistry to organic synthesis with specific attention to applications with complex molecules. Updates and expands chapters 13-20 of Principles and Applications of Organotransition Metal Chemistry, 2nd ed. (1987). Published by University Science Books, 20 Edgehill Rd., Mill Valley, CA 94941. Annotation copyright by Book News, Inc., Portland, OR
