η2-dpndy) (4), and the paddle-wheel complex [W(CO)3]2(μ,η2-dpndy)3 (5). Further treatment of W(CO)3(Me3tach) with 3 generates the tripodal compound W(CO)3[(μ,η2-dpndy)W(CO)3(η2-dpndy)]3 (6). The molecularstructures of 2 and 5 have been determined by an X-ray diffraction study.
1,3,5-Trimethyl-1,3,5-triazacyclohexane tricarbonyl complexes of Mo and W as sources of the fac-M(CO)3 fragment. Mild syntheses of fac-[M(CO)3(CH3CN)3] (M=Mo, W), [W(CO)3(PR3)3], [W(CO)(alkyne)3] and [W(CO)3(π-arene)] complexes

The 1,3,5-trimethyl-1,3,5-triazacyclohexane (Me(3)tach) group in [M(CO)(3)(Me(3)tach)] complexes (M=Mo, W) is easily displaced by a variety of ligands under mild conditions. The lability of the Me(3)tach ligand allows the [M(CO)(3)(Me(3)tach)] complexes to be used as synthetic intermediates in convenient syntheses of products such as fac-[M(CO)(3)(CH3CN)(3)] (M=Mo,W), [W(CO)(alkyne)(3)], [W(CO)(3)(PR3)(2)] and [W(CO)(3)(eta(6)-arene)] complexes. An improved synthesis of [W(CO)(3)(Me(3)tach)] from [W(CO)(6)] and Me(3)tach is described. (C) 1998 Elsevier Science S.A. All rights reserved.

Reaction of W(CO)(3)(Me(3)tach) (Me(3)tach=1,3,5-trimethyl-1,3,5-triazacyclohexane) with Ph(2)PCdropCPPh(2) at room temperature affords a triply-bridged complex W-2(CO)(6)(mu-Ph(2)PCdropCPPh(2))(3) (1) and a vinylidene complex W-2(CO)(6)(mu-Ph(2)PCdropCPPh(2))[mu-C4H(PPh2)(3)] (2). Compound 2 can be obtained by treating 1 with Me(3)tach in dichloromethane. The crystal structures of 1 and 2 are determined by an X-ray diffraction study. The structure of 1 depicts a helical M2L3 framework with an idealized D-3 symmetry. The vinylidene group of 2 is not linear, with the W=C=C bond angle of 158.6(4)degrees.
