An efficient synthesis of diarylallenylidene pentacarbonyl chromium and tungsten com­plexes is presented. Irradiation of M(CO)6 in THF affords (CO)sM[THF], Substitution of the THF ligand by diarylpropargylalcoholate and subsequent desoxygenation with COCF gives the title compounds in good yield. (The structure of diphenylallenylidene pentacarbonyl chromium has been determined by X-ray structure analysis

Molybdenum and tungsten nitrosyl complexes with dithiocarbamato ligands have been prepared and characterized by analysis, and 1H n.m.r, and infrared studies. The molybdenum complexes are formulated as seven-coordinate species [Mo(NCO)L(S2CNEt2)2NO]- (L = Cl-, N3-, NCS-),{Mo(NCO)(S2CNEt2)2NO}2N2H4 and [Mo(NCO)B(S2CNEt2)2NO](B = NH3, pyridine). Likely stereochemistries are discussed. New tungsten complexes have been prepared by photochemical reactions of cis-[W(S2CNEt2)2(NO)2] to give [WL2(S2CNEt2)2NO]-, [WL(S2CNEt2)2(Me2SO)NO](L = NCO-, N3-, NCS-) and [W(NCO)(S2CNEt2)2(MeCONMe2)NO]. Assignments for the nitrosyl infrared bands in cis-[MO(S2CNEt2)2(NO)2] and [Mo(NCO)(S,CNEt2)2(Me2SO)NO] havebeen made by using 15NO labelled ligands.
