| he cluster, ;A kinetic study on aromatic and aliphatic thiol desulfurization reactions mediated by 1 revealed that thiols reacted with 1 via an associative mechanism, and the rate determining step involved coordination of the thiol to 1. The activation parameters for the thiol desulfurization reactions suggested that a thiol adduct of 1 was an intermediate complex.;At low temperatures, thiolate anions initially coordinate to a Co atom in 1 to yield a red adduct. The structure of the adduct was confirmed by ;When 1 was allowed to react with thiolate anions in solution above 50;Clusters 1 and 2 reacted with thietanes to yield alkenes. With a mixture of cis/trans-2,4-diphenylthietane, 1 and 2 were stereoselective for the formation of cis-1,3-diphenylpropene. Whereas 1 yielded 2 as the organometallic complex, 2 formed the insoluble cluster... |
