| The use of high oxidation state transition metal compounds as reduction catalysts has attracted considerable interests due to their practicality in synthetic applications and the novel mechanistic aspects in silane activation. We have recently shown that a cationic oxorhenium oxazoline complex catalyzes the hydrosilation of ketones and aldehydes. Now this chemistry is extended to the tetradentate bis(salicylideneamine) ligands as well as other systems. A series of monooxo rhenium complexes, are prepared and shown to catalyze the hydrosilation of a variety of ketones and aldehydes, while the reactivity and selectivity vary with the carbonyl substrates, silanes, and ligands. Mechanistic understanding on the catalytic process will also be discussed. |
