## Abstract A general method has been developed for preparing enantioenriched secondary alcohols by starting from aryl bromides and aldehydes. Aryl bromides were first treated with BuLi, and the resulting aryllithium reagents were mixed with titanium tetraisopropoxide and magnesium bromide. The rea
Reactions under mild conditions of primary amines with an excess of an organolithium reagent furnish (after hydrolysis) unexpected products: a-substituted amines and ketones.
Network methylethoxypoly silanes containing various substituents such as phenyl, butyl, phenylene, thiophene, and anthracene groups were prepared by a dlsproportionation reaction of 1,1,2,2-tet raethoxy -1,2-dimethyldisilane initiated by addition of a small amount of organolithium reagents that have
