Electrochemical synthesis of substituted barbaralanes by reduction of bicyclo[3.3.1]nonadienediones in the second wave
Abstract
In contrast to the first wave reduction of 4,8-dimethylbicyclo[3.3.1]nona-3,7-diene-2,6-dione (1) or 4,6-dimethylbicyclo[3.3.1]nona-3,6-diene-2,8-dione (2) which give dimeric products, reduction in the second voltammetric wave gives substituted barbaralanes.
