Stereochemistry of acidolysis of cyclohept-2-enyl-silanes and -stannanes
Abstract
Direct 2H n.m.r. analysis of the 2H-substituted 3- and 4-methylcycloheptenes produced by acid cleavage (CF3CO2D) of mixtures of 4- and 7-methylcyclohept-2-enyltrimethyl-silanes and -stannanes confirms stereospecific γ-anti attack by the electrophile.
