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.
开发了一种新颖有效的合成N,N-二烷基氨基-O-烷基-2-(1-甲基-2-氧亚丙基)磷酰肼肟5的方法。该反应涉及二乙酰单肟和N,N-二烷基氨基的缩合-O-烷基磷酰肼在活性二氧化硅存在下发生反应,并在温和条件下以优异的收率得到相应的目标肟。
