Electroreduction of trans-[Mo(CN)Cl(Ph2PCH2CH2 PPh2)2] in the presence of phenol gives trans-[Mo(CNH2)Cl(Ph2PCH2 CH2PPh2)2], this is the first example of the conversion of co-ordinatedcyanide to the aminocarbyneligand, a reaction of relevance to reduction of cyanide by nitrogenase; the methyleneamide, trans-[Mo(NCH2)Cl(Ph2PCH2 CH2PPh2)2], is oxidised to the cyanide and therefore the redox reactions
