文摘

The use of N-alkyl-2-haloaldimines in the imine version of the Pudovik reaction, namely, in the reaction of imines with acid esters of phosphorus acids, much extended the synthetic potential of this reaction due to the fact that the primary addition and protonation product, having quite a mobile single hylogen atom, can undergo both spontaneous transformations and transformations involving other reagents. The reduction of the С–Hlg bond in N-alkyl-2-halo- and -2,2-dihaloaldiminium salts with О,О-dialkyl phosphorodithioic acids was observed for the first time.KeywordsN-alkyl-2-haloaldiminesdialkyl phosphorus acidsN-tert-butyl-2,2-dichloropropanamineaziridinium saltaziridinium ring opening
