摘要

The reactions of benzyne, generated by the thermolysis of benzenediazonium-2- carboxylate, with 1, l-dicyclopropylethylene (1), 2-cyclopropylpropene (6), and a- cyclopropylstyrene (1 1) are herein described. Benzyne shows no tendency to add acrass the vinylcyclopropane systems in 1, 6, and 11. With substrates containing proper allylic hydrogens, the “ene” reaction (6-.+ 7-t 10) exceeds that of [2+ 21 cycloaddition (6+. 9,). ...
