Hexalkylditin is prepared by a Lewis acid-promoted(MgCl/sub 2/) reductive reaction of bis(trialkyltin) oxide using magnesium metal as reducing agent. Hexabutyl- and hexaphenylditin are synthesized with 95% and 80% yield separately and a radical mechanism is proposed for the reaction condition. Unsymmetric ditin, Bu/sub 3/Sn- SnPh/sub 3/, was first synthesized by this reductive method.
