Thermal and photochemical reactions of rhodium(trialkylsilyl)hydride complexes: NMR and bonding of poly(silyl)(hydride) complexes
Abstract
Thermal reaction of (η5-C5H5)Rh(C2H4)(H)(SiR3) with R′3SiH (R, R′= Et, Me) generates the sterically hindered poly(silyl) complexes (η5-C5H5)Rh(SiR′3)2(SiR3)H, some of which contain an η2-silane ligand; these complexes undergo silyl migrations with an excess of silane and also prove photosensitive.
