52 - 197C-Phosphorylation of N,N-Dimethylhydrazones of Formaldehyde andCrotonaldehyde. — Reaction of the hydrazones of formaldehyde (I) andcrotonaldehyde (XI) with phosphorus tribromide and subsequent aminationaffords the first representatives of hydrazones bearing trivalent phosphorus atthe azomethine carbon or in a vinylogous position (VI) and (XIII), respec-tively. In contrast to the crotonaldehyde derivative (XI), the formaldehydehydrazone (I) also reacts with less active phosphines like compound (II). Thetransformation of the phosphines to pentavalent phosphorus derivatives as wellas their alkylation is studied. — (TOLMACHEV, A. A.; MERKULOV, A.S.; YURCHENKO, A. A.; SEMENOVA, M. G.; PINCHUK, A.
