  Synthesis of a Thiocarbamoyl Alkylidyne Complex and Caveats Associated with the Use of [Mo(≡CLi)(CO)₂(Tp*)] (Tp* = Hydrotris(3,5-dimethylpyrazol-1-yl)borate)

  摘要：

  The successive reactions of [Mo( CBr)(CO)(2)(Tp*)] (1; Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with '' BuLi and N,N'-dimethylthiocarbamoyl chloride provides as intended, via formation of [Mo( CLi)(CO)(2)(Tp*)] (2a), the thiocarbamoyl alkylidyne complex [Mo{ CC(=S)NMe2}(CO)(2)-(Tp*)] (3). Although the yields are poor, analysis of the side products obtained provides insights into caveats to be considered when employing the lithium/halogen exchange protocol in these systems: the 1-pentylidyne [Mo( C '' Bu)(CO)(2){HB(pzMe(2))(3)}] (4) would appear to arise from competition between '' BuBr and the electrophile of choice, and Templeton's nonclassical vinylidene [Mo-2-(mu-CCH2)(CO)(4)(Tp*)(2)] (5a) most likely arises under strictly anhydrous conditions from '' BuBr acting as a proton donor (i.e., E-2) rather than electrophile (S(N)2). The formation of the ethanediylidyne [Tp*(CO)(2)Mo CC Mo(CO)(2)(Tp*)] (6) may be accounted for by single-electron-transfer (outer-sphere) oxidation of 2 to provide the radical carbido complex [Mo( C-center dot)(CO)(2){HB(pzMe(2))(3)}] (7), which dimerizes to provide 6. The dimer 6 is also formed alongside 5a in the reaction of 2 with [Fe(eta-C5H5)(2)]PF6, supporting the intermediacy of 7 in the formation of 6.
