| Abstract: | The reaction of anilides with the titanium carbene complexes generated by the desulfurization of thioacetals with the titanocene(II) species Cp2TiP(OEt)3]2 produced the corresponding enamines. Unusual formation of pyrrolidines was observed when N-3,3-bis(phenylthio)propyl]anilides were treated with the titanocene(II) reagent. |
