โœฆ Synopsis


Triorganometal chlorides, R3MCl (R = alkyl, aryl; M = Si, Sn) are readily coupled to form bimetallics in 42-95% yields using Li wire and ultrasound.

Dihalosilanes give good yields of cyclic polysilanes.

Rare earth metals (Ln) are found to act as useful reducing agents for the pinacol coupling reaction of alkyl aryl ketones in the presence of chlorosilanes. Although the hitherto known pinacol coupling reaction using rare earth reducing agents generally exhibits very low diastereoselectivities, the p

## Abstract Reductive homocoupling of aromatic aldehydes, ketones, and imines has been achieved in tetrahydrofuran (THF) at room temperature using a catalytic amount of InCl~3~ (0.5โ€“3.0 mol %) under a nitrogen atmosphere in the presence of chlorotrimethylsilane (TMSCl) and aluminum metal (Al) to pr
