Reactive phosphonium ylides based on 3-phenyl-3-chloro-2-aza-2-propen-1-yl(triphenyl)phosphonium chloride

Treatment of the accessible phosphonium salt PhCCl=NCH2P+Ph3Cl- with triethylamine yields a solution of biphilic ylide PhCCl=NCH=PPh3, which along with the nucleophilic center of the P=C bond contains an electrophilic imidoyl chloride group and therefore enters cyclocondensations with carboxylic acid chlorides, carbon disulfide, and acyl isothiocyanates. The latter cyclization is of particular significance because it yields previously inaccessible (5-acylimino-2-phenyl-4,5-dihydrothiazol-4-ylidene)triphenylphosphoranes, which, in turn, were used to prepare a series of new derivatives of 5-benzoylamino-2-phenylthiazole. Reaction of the above-mentioned phosphonium salt with sodium thiocyanate in the presence of triethylamine apparently yields the unstable intermediate ylide PhC(NCS)=NCH=PPh2, which is stabilized by intramolecular cyclization to give 5(4)-thioxo-2-phenyl-4,5-dihydroimidazol-4(5)-ylidenetriphenylphosphorane. 1999 MAEe cyrillic signK "Hayκa/Interperiodica".

REACTIONS OF 1-ARYL-1,4,4-TRICHLORO-2-AZA-1,3-BUTADIEN-3-YLTRIPHENYLPHOSPHONIUM SALTS WITH THIOUREA AND SELENOBENZAMIDE

Substituted vinylphosphonium salts, which contain a specific fragment, Cl2=C()N=CClAr, are easily condensed with thiourea and selenobenzamide to give the corresponding 4-phosphorylated 2-aryl-5-chlorothi(selen)azole derivatives.The latter contains a mo
