Abstract
1. The alcohol 1-(3′,3′-diphenyl-3′-hydroxy-1′-propyn-1′yl)-4-(ethynyl)benzene and its aminomethyl-ation products undergo normal Meyer-Schuster rearrangement, forming the corresponding vinyl ketones and amino ketones. 2. In acid medium, in the presence of HgSO4, 1-(1′-hydroxycyclohexylethynyl)-4-(ethynyl)benzene and its aminomethylation products undergo dehydration, with subsequent hydration of one of the triple bonds to the corresponding acetylenic ketones and amino ketones.
