  Exploring the reactivity of alkenes bearing silicon and/or tin in the hydroxyl-directed hydrogenation. A diastereoselective synthesis of heterobimetallic compounds

  摘要：

  The hydroxyl-directed hydrogenation of (E)- and (Z)-gamma-hydroxy vinylstannanes and silanes has been studied in the presence of (dppb)Rh(NBD)BF4 (1). Efficient routes to gamma-hydroxy stannanes and silanes have been developed. Diastereoselectivities from 60 to >500:1 were observed. A significant difference in reaction rate and pathway was observed between the (E)- and (Z)-vinylstannanes. We observed a reductive destannation process for the (Z)-stannanes which was influenced by the size of the R group. Competition studies were carried out to determine if steric or electronic effects were responsible for the reactivity patterns observed.
