Recent advances in the asymmetric hydrosilylation of ketones, imines and electrophilic double bonds
This literature review focuses on the recent advances in the asymmetric hydrosilylation of ketones and imines. New catalyst systems based on various transition metals, such as rhodium, titanium, zinc, copper and tin, combined with classical or new ligand structures, are presented. These systems lead to very effective and selective protocols for the reduction of prochiral ketones, imines and electrophilic double bonds
Efficient enantioselective hydrosilylation of ketones catalyzed by air stable copper fluoride-phosphine complexes.
[reaction: see text] Copper(II) fluoride-chiral diphosphine systems catalyze the hydrosilylation of several ketones with moderate to excellent enantioselectivities. An oxygen acceleration effect was observed and led to a practical protocol with low catalyst loading
New efficient copper fluoride-based catalyst for enantioselective hydrosilylation of ketones in aerobic conditions
A new copper(II) fluoride-chiral diphosphines catalytic system was developed. This one is very efficient and selective for the hydrosilylation of several substituted or unsubstituted aromatic ketones in so far as moderate to excellent enantioselectivities were obtained. An oxygen acceleration effect was observed that led us to propose a practical protocol with a low amount of catalyst
