SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Sundargopal Ghosh
DESCRIPTION:Title: “Coordination Chemistry of Diborane(4) and Diborane(6)” \nAbstract: The fascinating aspect of metallaborane chemistry is that several classic organometallic complexes that defined fundamental structural and bonding paradigms are mimicked by many isoelectronic metallaborane analogues.[1] In this connection\, diborane compounds not only mimics several classic organometallic compounds but also they have been extensively explored for the broad understanding of the chemical bonding and catalysis.[2] For example\, we have recently synthesized and structurally characterized a bimetallic diborane(4) which mimics Cotton’s dimolybdenum–alkyne complex [{CpMo(CO)2}2C2H2].[3] Also\, we have isolated the first classical diborane(5) [B2H5]-\, in which the sp2-B center is stabilized by the electron donation from tantalum.[4] Very recently\, we have developed an uncatalysed synthetic pathway to generate the doubly base stabilised symmetrical and unsymmetrical diborane(4) species from the thermolysis reaction of 2-mercaptopyridine with [BH3.THF]. The key results of this work will be described.
