摘要

cis-1-Mesityl-2-phenylcyclopentane (cis-I) has been found to undergo rotation of the mesityl ring slowly enough to permit detection by a change in nmr line shape at low temperatures. At the coalescence temperature (-44”), the rate of rotation is approximately 160 sec-1. Cyclobutylmesitylphenylmethane (1x1, 3-bromomesitylcyclobutylphenylmethane (X), isopropylmesitylphenylmethane (XI), and p, B'-dimesityladipic acid (XIII) and its ester XI1 ...
