Bromo-derivatives of dimethyl 4-oxo-trans-2,6-diphenylcyclohexane-1,1-dicarboxylate and their dehydrobromination
Abstract
The structures and stereochemistry of various bromo-derivatives of dimethyl 4-oxo-trans-2,6-diphenylcyclohexane-1,1,-dicarboxylate are reported. The dehydrobromination of these derivatives is described and, in some cases a phenol is produced by demethoxycarbonylation.
