摘要：

(Chemical Equation Presented) Activity without mobility: A compact trialkylphosphane, chemically immobilized on a silica gel surface (see picture), exhibited unique coordination behavior to form a 1:1 Rh/P complex. The monophosphane-{RhCl(cod)} species on the surface was highly active for catalysis of the hydrosilylation of ketones, allowing the conversion of di(tert-butyl) ketone into the corresponding TBS-protected alcohol. TBS = tert- butyldimethylsilyl; cod = 1,5-cyclooctadiene. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
