Abstract
Abstract 3-Methoxy-1-phenyl-1-propyne treated at −75° by two equivalents of butyl-lithium in ether gives a dianion whose structure is allenic. This dianion offers various possibilities of selective mono and bialkylation rections with excellent yields. Hydrolysis of allenic ether derivatives liberates α-ethylenic aldehydes or ketones.
