Time resolved infrared spectroscopy solvent effect

Reports of new tungsten complexes include the reaction of the transient species W(CO)5(cyclohexane) with cyclo-C4H 0 (n = 4, 6, 8) studied by time-resolved infrared absorption spectroscopy. Schultz and co-workers have noted an unusual solvent isotope effect in the reaction of W(CO)5(solv) (solv = cyclohexane or cyclohexane-rfu) with TFIF. Some interesting chemistry involving W(CO)5(2,5-dihydrofuran) is noted by the same group. Adducts of cyclotriphosphorus complexes have been reported by Di Vaira and co-workers, leading to the synthesis, solid state structure and solution behaviour of the bis-adducts [ (MeC(CH2PPh2)3)Co (P3)(M(CO)5 2], where M is a Group 6 metal.
