Mechanism of an Interesting Ring-Contraction Reaction of a Class of Carbocyclic trans-Dibromides and Stereoisomeric Bromohydrins through Solvolysis

An efficient ring contraction of the trans-dibromides and the bromohydrins (1a-f) through solvolysis under neutral conditions to the aldehydes (3a-d) in good to excellent yields is reported.The role of substituent, influence of stereochemistry, and the effect of ring size on the case of this interesting ring contraction reaction are clearly demonstrated from the results, tabulated in Table 1; a probable mechanism for ring contraction is presented.
