Synthesis, characterisation and reactivity of group six alkylidynes bearing the tridentate phosphine PPh(C2H4PPh2)(2) 'triphos'. Crystal structure of mer-[W(NCMe)( CC6H4Me-4){PPh(C2H4PPh2)(2)}(CO)][BF4]
Reaction between [WBr(≡CC6H4Me-4)(NC5H5Me-4)2(CO)2] and the tridentate, linear, phosphine PPh(CH2CH2PPh2)2 (triphos) in refluxing toluene affords mer-[WBr(≡CC6H4Me-4){PPh(C2H4PPh2)2}(CO)], 1. Halide abstraction (with TIBF4) in CH2Cl2 solvent results in carbonyl scavenging to afford the cationic dica...
