Abstract
Under polar conditions asymmetric hexaalkylditins, R3SnSnR′3, disproportionate rapidly at room temperature to give the symmetrical ditins R6Sn2 and R′6Sn2. The equilibrium constants observed for a series of such reactions (R = Me; R′ = Et, Pt, Bu, i-Bu) point to a predominance of steric rather than inductive effects.
