Synthesis of Fischer type-carbene complexes containing a coordinated thioimidate structural motif

Author affiliations

Abstract

This paper describes a tandem strategy to synthesize a series of new Fischer carbene complexes [(CO)4M[double bond, length as m-dash]C[N–(CH2)4–]CH[double bond, length as m-dash]C(NRR′)(SR′); M = Cr, W; R = Ar, R′ = Me, –(CH2)2–] with a thioimide or thiazoline fragment, in which the sulfur or nitrogen atom is coordinated to a metal center, depending on the nature of alkylating groups included as R′. We have trapped by protonation the proposed intermediate as the thioamide 12 [(CO)5W[double bond, length as m-dash]C[N–(CH2)4–]CH2C(S)NHPh], which reveals the pathway of this reaction
