Abstract
Abstract Treatment of di-t-butyldichlorostannane with sterically congested aryllithium compounds gives di-t-butylchloro(mesityl)stannane ( 2 ) and di-t-butylchloro(2,4,6-tri-t-butylphenyl)stannane ( 3 ), both of which show restricted rotation about the SnC(Ar) bond at room temperature. Reductive chloride elimination from 2 yields the corresponding distannane, whereas a similar reaction of 3 only results in decomposition. Reaction of 3 with t-butyllithium by hydrogen abstraction from one of the ortho -t-butylmethyl groups gives the stannaindane derivative ( 6 ). The structures of 3 and 6 have been confirmed by X-ray crystallography.
