摘要

Abstract The Grignard reagent from 5-chloro-3-methyl-1-hexene cyclized reversibly to form an equilibrium mixture with two stereoisomers of the 2, 4-dimethylcyclobutylmethyl-Grignard reagent. Equilibrium and rate constants for the opposing reactions have been evaluated at 80–100 and 100–120 C, respectively. Over this range, the equilibrium mixture favors the cyclic reagent by a ratio of about Full-size image (< 1 K)
