2-BENZOPYRYLIUM SALTS. 42. ORTHO-QUINOID INTERMEDIATES IN RECYCLIZATION REACTIONS OF 2-BENZOPYRYLIUM SALTS

Verin, S.V.,Tosunyan, D.E.,Kuznetsov, E.V.

, p. 1183 - 1189 (1991)

The interactions of 1-styryl-substituted 2-benzopyrylium salts with morpholine, methylamine and malononitrile is highly stereoselective in forming cis-3,4-dihydronaphthalenes; this can be taken as evidence that ortho-quinoid intermediates participate in t
