Carbene and carbonyl transfer from [W(CO)5(carbene)] to palladium, affording palladium(II) carbene acyl complexes

The reaction of [W(CO)5{C(NEt2)Ph}] (3) with [PdClR(SMe2)]2 (R = Me, Ph) occurs with transfer of carbene and carbonyl groups to give [PdCl{C(O)R} {C(NEt2)Ph}] 2 (R = Me, 4; R = Ph, 5). When

Sulfur Ylide Complexes via Addition of Thioethers to Benzylidenepentacarbonyltungsten

Benzylidenepentacarbonyltungsten, (CO)5W (1), reacts with thioethers, SR2 (2), to give the sulfur ylide complexes (CO)5W (SR2 = SMe2 (3a), SEt2 (3b), SC4H8 (3c)).The thermolysis of 3a and 3b yields mainly (CO)5W(SR2) (4a,b), respectively.Additionally, cis-(CO)4W(SR2)2, 2 and W(CO)6 as well as cis- and trans-stilbene are formed.The complexes 3 react with PPh3, via SR2/PPh3 exchange to give (CO)5W.In the reaction of 3b with olefins such as 1-hexene and ethyl vinyl ether the C(H)Ph group is transferred to the olefinic double bond and cyclopropanes are formed.In contrast to the reaction of 1 with thioethers that with dimethyl sulfoxide does not yield a stable ylide complex but rather benzaldehyde via oxidative elimination of the benzylidene ligand.The (CO)5W fragment is stabilized as (CO)5W(SMe)2 (4a).
