Abstract

Abstract Quaternary ammonium salts with a 1, 1-dimethylbut-2-yne-1, 4-diyl common group react with aqueous alkali with intermediate formation of 1, 2-rather than 1, 4-cleavage products. When both nitrogen atoms bear allylic groups, rearrangement-cleavage- substitution occurs to give methyl isopropyl ketones. Salts with two 3-methylbut-2-en-1-yl groups cleave isoprene.
