A novel and efficient method has been developed for the synthesis of N,N-dialkylamino-O-alkyl-2-(1-methyl-2-oxopropylidene)phosphorohydrazido oximes 5. The reactions involve the condensation of diacetylmonoxime and N,N-dialkylamino-O- alkylphosphorohydrazides in the presence of activated silica and give the corresponding target oximes in excellent yields under mild conditions.
已开发出一种新颖且高效的方法来合成N,N-二烷基氨基-O-烷基-2-(1-甲基-2-氧代亚丙基)磷酰肼肟5。反应涉及二乙酰单肟与N,N-二烷基氨基-O-烷基磷酰肼在活化硅胶存在下的缩合反应,并在温和条件下以优异的产率得到相应的目标肟。
