Kinetic and stereochemicalstudies have been conducted on the reaction of (arylthio)trimethylgermanes with 1-aryl-1-bromoethanes. The reaction has been found to obey a first-order kinetic equation. The rates of the reaction of the substituted arylethanes were well-correlated with σ+ constants. Optically active 1-bromo-1-phenylethane gave racemic phenyl 1-phenylethyl sulfide by the reaction with trim
