Abstract
This paper describes a tandem strategy to synthesize a series of new Fischer carbene complexes [(CO)4MC[N–(CH2)4–]CH
C(NRR′)(SR′); M = Cr, W; R = Ar, R′ = Me, –(CH2)2–] with a thioimide or thiazoline fragment, in which the sulfur or
C[N–(CH2)4–]CH2C(S)NHPh], which reveals the pathway of this reaction
