Abstract

The oxidation of a,P-dihydrazones with various mercury and silver salts to produce acetylenes has long been However, it is believed that the following is the first reported direct synthesis of acet- ylenes from monohydrazones. The reaction involves oxidation of substituted benzyl ketone hy drazones with mercurous trifluoro- acetate in refluxing ether or in dioxane at 40-50' according to the eq 1. Oxygenated solvents which ... (1) T. Curtius, E'er., 22, 2161 (1889). (2) T. ...
