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.

AN INTERESTING RING CONTRACTION OF A CLASS OF BROMOHYDRINS AND TRANS-DIBROMIDES

An efficient ring contraction of stereoisomeric 1,2-benzo-4-bromo-3-hydroxycyclohept-1-ene and their derivatives (1a-e) to (2a-c) is reported, and a probable mechanism for this ring contraction has been suggested.
