Reactions of [Ir(COD)(PMe3)3]Cl with heteroaromatic compounds: Formation of an iridathiacycle, an iridaselenacycle and iridaazathiacycles
摘要:
Reactions between [Ir(COD)(PMe3)(3)]Cl, 1, and the heteroaromatic compounds thiophene, selenophene and thiazole (and substituted thiazoles) are reported. Compound 1 acts as a convenient source of the very electron-rich "Ir(PMe3)(3)Cl" which is very active for oxidative addition reactions. All of the heteroaromatic compounds mentioned add via C-S or C-Se oxidative addition resulting in the insertion of the iridium forming 6-membered thia- or selena-iridacycles.[GRAPHICS].
