Remarkable effects of remotely connected but spatially proximate hydroxy-groups on the brich reduction of o-xylene moieties
Abstract
Brich reductions of the syn-alcohols (1c) and (6)(where the OH group is the substituent on the methano-bridge nearest to the aromatic ring) were atypical in that they were extremely rapid and have products (3) and (7) respectively; these results are explained by the ability of the proximate hydroxy-group to act as an efficient proton source.
