A Lewis acid-promoted reduction of acylsilanes to α-hydroxysilanes by diethylzinc
摘要:
We report here the first example of the reduction of acylsilanes to alpha-hydroxysilanes, in which diethylzinc was used as a highly reactive agent in the presence of Ti(OiPr)(4) or other Lewis acids. The reduction typically proceeds to give synthetically useful alpha-hydroxysilanes in good yields. (c) 2012 Elsevier Ltd. All rights reserved.

hydroperoxidatedcarbonyl compounds derived from the Michael reaction of 5,5-dimethylcyclohexane-1,3-dioneand chalcone, is reported. A series of aromatic acylsilanes withTBDPS were obtained in promising isolated yields. In addition, asan extension of the relay oxidation under aerobic conditions, thiscatalyst-free relay oxidation induced by diketone can be appliedto the oxidation of general aromatic alcohols
