[Re2(CO)10] and PR3[PR3= PPh3, PMePh2, PMe2Ph, PMe3, P(CH2Ph)3, or P(OMe)3] in xylene is catalysed by Pd/C, Pd/CaCO3, and PdO and yields the complexes [Re2(CO)10–n(PR3)n](n=1 or 2) as the major products (15–80%). Attempts to synthesise [Re2(CO)10–n(PR3)n] from [Re2(CO)10] and PR3in the presence of NMe3O under milder conditions (e.g. refluxing CH2Cl2) also gave the above products with n=1 or 2 as well

radicals, Re(CO)sub 4}L* (L = PMesub 3} or P(O-i-Pr)sub 3}), generated via flashphotolysis at 22degree}C of acetonitrile solutions of the corresponding dinuclear compounds, Resub 2}(CO)sub 8}Lsub 2}, are observed to undergo electron transfer to substituted N-methylpyridinium cations. Reaction rates were measured by observing the disappearance of the transient absorption due to Re(CO)sub 4}L* or
