Platinum complex hydroboration

This chapter describes how the use of JV-heterocychc carbenes (NHCs) has enabled the discovery of unique platinum(O) catalysts for the hydrosilylation of unsaturated carbon-carbon bonds. Independently, a similar strategy has been explored by Elsevier and coworkers [9]. NHC platinum(0) complexes have also been used as hydroboration and diboration catalysts as well as precursors of platinum(II) carbene complexes [10]. Supported platinum carbene complexes on mesoporous cross-linked polystyrene particles, precipitated siUca and porous glass beads have been reported as well as their application in hydrosilylation [11]. Water-soluble analogs have also been prepared [12]. These will not be discussed here.
