The reaction of 3, 3-diacetyl-1-acyltriphenylphosphonium allylides (4) with bases gave 5-substituted 2-acetyl-4-triphenylphosphoniophoniophenolates (5) and 5-substituted 4-acetyl-2-triphenylphosphoniophenolates (6). These structures were established by chemical and ultraviolet spectral methods. On the other hand, deacetylation occurred by the treatment of 4 with 10% hydrochloric acid to give 3-acetyl-1-acyltriphenylphosphonium allylides (18). 3, 3-Diacetyl-1-benzoyltriphenylpuhsphonium allylide (4a) was pyrolyzed to 1, 1-diacetyl-4-phenylbutenyne (17).
