Synthesis and reactions of phenylcarbamoylarylhydrazidic chlorides

Chemistry of carbofunctionally substituted hydrazones

“…Scheme 4). Ethyl acetoacetate 15a [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] ethyl cyanoacetate 15b, [51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] cyanoanilides 15c, [67][68][69] benzoylacetonitrile 15d 70 and cyanothioacetamide 15f 71,72 couple readily with aromatic diazonium salt in presence of sodium acetate to yield corresponding arylhydrazones whose exact geometry has only been recently established 16 (cf. Scheme 5).…”
