Ao. Abdelhamid et Gs. Mohamed, Reaction with hydrazonoyl halides XXIII [1]: Synthesis and reactions of C-coumarinoyl-N-arylformohydrazonoyl bromides, HETEROAT CH, 10(5), 1999, pp. 355-362
C-Coumarinoyl-N-arylformohydrazonoyl bromides (3) were synthesized by react
ion of N-nitrosoarylacetamides with an appropriate sulfonium bromide in eth
anol at room temperature, The reactions of potassium thiocyanate, potassium
selenocyanate, thiorea, methyl phenylthiocarbomate, and methyl phenylhydra
zinedithioate with hydrazonoyl bromide 3a were examined. (C) 1999 John Wile
