separated from the reaction of neopentyl diphenylphosphinite with α-chloroacetophenone at O° and was shown to yield neopentyl chloride and the corresponding Perkow product by a first-order process in chloroform (t12 ca 40min at 33°). It is suggested that the betaine formed by initial attack of phosphorus at the carbonyl carbon atom may be a common first intermediate in reactions that yield both Arbuzov and
已经分离出结晶的酮基溴化膦作为亚磷酸三戊酯,二戊基苯基苯基膦酸酯和新戊基二苯基亚膦酸酯与α-溴苯乙酮反应的中间体。在每种情况下,溶液中的热分解都会产生新戊基溴化物和相应的Arbuzov产物。不会重新排列到Perkow中间体或产品上。在O°下从新戊基二苯基次膦酸酯与α-氯苯乙酮的反应中分离出可识别的Perkow中间体,并通过氯仿的一级反应显示出可产生新戊氯和相应的Perkow产物(t12 ca在33°下40分钟)。建议由磷在羰基碳原子上的初始进攻而形成的甜菜碱可能是产生Arbuzov和Perkow产物的反应中常见的第一中间体
