Coordination chemistry of diborane(4) and diborane(6)

The fascinating aspect of metallaborane chemistry is that several classic organometallic complexes that define fundamental structural and bonding paradigms are mimicked by many isoelectronic metallaborane analogues. In this connection, diborane compounds not only mimic several classic organometallic compounds, but they have also been extensively explored for a broad understanding of chemical bonding and catalysis. For example, we have recently synthesised and structurally characterised a bimetallic diborane(4), which mimics Cotton's dimolybdenum-alkyne complex [{CpMo(CO)2},C2H2]. Also, we have isolated the first classical diborane(5) [B2H5], in which the sp2-B centre is stabilised by the electron donation from tantalum. 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 ofthis work will be described in the talk.
