Abstract

Abstract 1-(Diphenylmethylene)-2 (1 H)-naphthalenone (1) reacts with trialkyl phosphites to give the corresponding 1, 2-dihydro-2-alkoxy-1, 1-diphenylnaphth [1, 2-d-][1, 2]- oxaphosphole-2-oxides (3a-c). The latter compounds are equally obtained by the reaction of dialkyl phosphites with 1. A mechanism for this reaction is presented which accounts for the experimental results. On the other hand, 4-(diphenylmethylene)-1 (4 H)-naphthalenone (2 ...
