The deuteration of alpha-selenylated-beta-silylsulfoxides and alpha-se
lenylated-beta-tert-butylsulfoxides has been shown to lead, with good
levels of diastereocontrols to the formation of syn isomers irrespecti
ve of the stereochemistry of the sulfinyl precursors. Our results have
been rationalized using transition state models which parallel the Fe
lkin-Anh model. Copyright (C) 1996 Elsevier Science Ltd
