Manganese complexes isocyanide

The reaction of Mn(CO)jBr and methyl isocyanide was also carried out (Table V) the products are analogous to those obtained from phenyl isocyanide and the manganese complex.

There are no routes yet to homoleptic metal isocyanide anions. If one considers the interesting products obtained from methyl iodide additions to molybdenum (43) and manganese (44) carbonyl isonitrile anions, negatively charged isocyanide complexes should have some interesting chemistry. Also, now that a simple route to [CpFe(CNR)2]2 complexes has been devised (45), the synthesis of the anion [CpFe(CNR)2] could provide a route to a range of products including heterometal-metal bonded systems. 

Other Manganese(i) Complexes.—Treatment of Mn(N03)2,6H20 with high-boiling isocyanides RNC (R = p-anisyl, p-tolyl, or benzyl) in methanol under vacuum yields [Mn(CNR)g](N03)2 and/or [Mn(CNR)g](N03). The bivalent products can be converted into the univalent state by treatment with aceto-nitrile. ...
