- W2061330889 abstract "Reaction of [Mo(CCH2But){P(OMe)3}2(η-C5H5)] with HBF4·(MeCO)2O affords the crystallographically identified hydrido–carbyne [MoH(CCH2But){P(OMe)3)2(η-C5H5)][BF4][Mo–H, 1.74(3)Å]. In contrast, reaction with CF3CO2H or CF3SO3H leads to loss of the carbyne fragment and the formation of [Mo{σ-OC(O)CF3){η2-HOC(O)CF3}{P(OMe)3}2(η-C5H5)] and [Mo(σ-OSO2CF3)(η2-HOSO2CF3){P(OMe)3}2(η-C5H5)], the former being structurally identified by X-ray crystallography. The reaction of [Mo(CCH2But){P(OMe)3}2(η-C5H5)] with Ph2PH and tetracyanoethylene was also examined. The phosphine reaction also leads to loss of the CCH2But group, with formation of [Mo(PPh2)(HPPh2){P(OMe)3}(η-C5H5)] and [Mo(PPh2){P(OMe)3}2(η-C5H5)]. Both of these complexes are also formed on reaction of Ph2PH with [Mo(η3-1 -MeC3H4){P(OMe)3}2(η-C5H5)]. Tetracyanoethylene reacts at room temperature with the carbyne to displace one of the trimethyl phosphite ligands with formation of the X-ray crystallographically characterised alkene-carbyne complex [Mo(CCH2But){η2-C2(CN)4}{P(OMe)3}(η-C5H5)]. The carbon-carbon bond of the co-ordinated tetracyanoethylene is orthogonal to the MOC vector." @default.
