Push-Pull Substituted Allenes, VI. Synthesis and Properties of 1,1-Diethoxy-3-acylallenes
Reaction of the non enolizing 1,2-diketones 1 with (2,2-diethoxyvinylidene)triphenylphosphorane (2) yields the 1,1-diethoxy-3-acylallenes 4 via the remarkably stable oxaphosphetanes 3.With two exceptions these allenes dimerize spontaneously to form the po
