Abstract

Ethoxyethynylcarbinols, which can be prepared from carbonyl compounds and metallic derivatives of ethoxyacetylene, react with amines in three dif- ferent ways. Strongly basic amines like diethylamine mainly cause reaction A, dis- sociation of the carbinol into the carbonyl compound from which the carbind was derived, and ethoxyacetylene (which reacts further with the amine used). Very weakly basic aromatic amines like pdtroaniline catalyze the rearrangement into a,@- ...
