    substituted with Me3C6H2NH2 or i-BuNH2 to yield (PhN)W(CO)2X2L (X = Cl or Br, L = Me3C6H2NH2 or i-BuNH2) or with PMe3 to produce (PhN)W(CO)Br2(PMe3)2. The oxidation of 1 with BrI resulted in the formation of [(PhN)W(CO)2Br(I)]2, which reacts with MeCN to produce (PhN)W(CO)2Br(I)(MeCN). The structures of the dimers [(PhN)W(CO)2X2]2 were determined by X-ray crystallography.

    [(CO)2W(NPh)I2]2 (1) has been demonstrated to be a catalyst for the oxidative carbonylation of primary amines to 1,3-disubstituted ureas. The amine complexes (CO)2I2W(NPh)(NH2R) [R = n-Bu (2a), R = n-Pr (2b), R = t-Bu (2c)] and [(CO)2IW(NPh)(NH2R)2]+ [R = n-Bu (4a), R = n-Pr (4b)] have been isolated from reactions of 1 with primary amines. Complexes 2a−c and 4a−b have been shown to lie along the pathway to the catalytically

    Reaction of the zwitterion (CO)5WNPhNPhC(OMe)Ph (1) with 1 equiv of I2 produces the iodo-bridged imido dimer [(CO)2W(NPh)I2]2 (2) and the imidate PhNC(OMe)Ph. Oxidation of 1 with 2 equiv of I2, however, leads to the formation of the unusual 16-electron tungsten(VI) metallacycle I3(PhN)WNPhCPhO (8). The structure of 8 was determined by X-ray crystallography. Mechanistic studies on the formation of both

    Reaction of [(CO)2W(NPh)I2]2 (1) with 2 equiv of piperidine yielded (CO)2W(NPh)I2(pip). In the presence of excess amine, secondary amines (R2NH) were carbonylated to the formamides R2NCHO while primary amines (R‘NH2) were converted to the ureas R‘NHCONHR‘.

    Reaction of the iodo-bridged tungsten dimer [(PhN)W(CO)(2)I-2](2) with 2 equiv of LiOCH3 produced new dimers of the type [(PhN)W(CO)(2)I(OCH3)](2). The intermediate iodo-bridged dimer [(PhN)W(CO)(2)(mu-I)(OCH3)](2) (5) reacted with PMe3, P(OMe)(3) or NH2C6H2Me3 to yield mononuclear derivatives of the type (PhN)W(CO)I(OCH3)L-2 [for 10: L=PMe3, for 11: P(OMe)(3)] or (PhN)W(CO)(2)I(OCH3)(NH2C6H2Me3) (9). In solution, 5 slowly isomerized to [(PhN)W(CO)(2)I(mu-OCH3)](2) (6), for which an X-ray crystal structure confirmed the presence of bridging methoxide ligands. Further reaction of 6 with excess LiOCH3 resulted in substitution of methoxide for the remaining iodides of 6 to produce. [(PhN)W(CO)(2)(OCH3)(2)](2) (7) in low yield. (C) 1998 Elsevier Science Ltd.
