摘要

Addition of photolytically generated carboethyxoycarbene as well as the copper carbenoid species to 1, l-dimethylallene (1) gives cyclopropanation of both of the allenyl double bonds of 1. Also produced are small amounts of 1-carboethoxymethylene-2, 2- dimethylcyclopropanes 4 and 5 as well as CH insertion products 6 and 7 in the case of the photolytically generated carbene. The photosensitized triplet carbene addition gives ...
