Reactions of stereochemically rigid diisocyanides with manganese carbonyl derivatives

Abstract

The reactions of BrMn(CO) 5 with the non-chelating stereochemically rigid bidentate ligands (L-L) 1,3-, and 1,4-diisocyanobenzene, 4,4′-diisocyanobiphenyl, and 4,4′-diisocyanodiphenylmethane afford well characterized complexes of the types BrMn(CO) 4(L-L), BrMn(CO) 3(L-L) 2, and [BrMn(CO) 4] 2(L-L). Similar reactions with [RC 5H 4Mn(CO) 2NO] +PF 6 − gave mixtures of oligomers of the type [(RC 5H 4MnNO) n (L-L) n+1 ] n+ [PF 6 −] n .
