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 Sn-C(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.
