✦ Synopsis

Very little is known about the reactions of phosphorus ylides with a-imino carbonyl compounds. Treatment of monoximes and monohydrazones of a-diketones with triphenylvinylphosphonium bromide gave moderate yields of 1 -hydroxypyrroles, 1 -aminopyrroles, or 2,3-dihydropyridazines '). The formation of five-and sixmembered rings appears to be dependent upon the geometry of the Scheme 1 / \ NOH Ph,P-CHCOOCH, &CHCOOCH3 / \ NOH 2 3(1,11)
