摘要

Steric hindrance could be augmented by replacing the methyl groups of 1 with bulkier phenyl groups. For this reason, 1, 1, l12-tetraphenylethane (4) was prepared from benzylmagnesium chloride and triphenylchloromethane.” As the reaction of 4 with NBS in refluxing carbon tetrachloride proceeded, an orange-brown vapor, identified as bromine, was observed. The appearance of bromine presages an elimination of hydrogen bromide ...
