Chemistry of μ-dithiobis(tricarbonyliron), an inorganic mimic of organic disulfides: II. Nucleophilic SS bond cleavage by organolithium and organomagnesium reagents☆

Abstract Organolithium and Grignard reagents cleave the SS bond of (μ-S 2 Fe 2 CO 6 at −78°C to give intermediates of type (μ-RS)(μ-MS)Fe 2 (CO) 6 , (M = Li or MgX). These may be alkylated with organic halides to produce complexes of type (μ-RS)(μ-R′S)Fe 2 (CO) 6 and protonated to yield (μ-RS)(μ-HS)Fe 2 (CO) 6 .

Mixed (μ-alkane- and arenethiolato)(μ-phosphido)hexacarbonyldiiron complexes. Synthesis and PCl reactivity

Abstract Reactions of the Et3NH+ or Li+ salts of the [(μ-CO)(μ-RS)Fe2(CO)6]− anions (R = tBu, Et, Ph) with chlorophosphines (PCl3, Ph2PCl, PhPCl2, CH3PCl2) gave (μ-Cl2P)(μ-RS)Fe2(CO)6 (R = tBu, Et, Ph), (μ-Ph2P)(μ-RS)Fe2(CO)6 (R = tBu, Et), (μ-PhPCl)(μ-EtS)Fe2(CO)6 and (μ-CH3PCl)(μ-EtS)Fe2(CO)6. Reactions of the complexes that contain PCl bonds with NH3 and amines and with alkanethiols are described.
