The coordination chemistry of iminooxosulphuranes. IV. The reactions of [WH(CO)₃(η-C₅H₅)] with iminooxosulphuranes and diiminosulphuranes

Abstract

The tungsten hydride [WH(CO)3(η-C5H5)] reacts with iminooxosulphuranes, RNSO (R = C6H4Me-2, C6H4Me-4), to give the tungsten sulphinamides [W{S(O)NHR}(CO)3(η-C5H5]. Diiminosulphuranes bearing electron-withdrawing substituents, R′NSNSO2C6H4Me-4 (R′ = C6H5, SO2C6H4Me-4), insert into the metalhydrogen bond of [WH(CO)3(η-C5H5)] to give [W{S(NR)NHSO2C6H4-Me-4}(CO)3(η-C5H5)], whilst bis(p-tolylimino)sulphurane, S(NC6H4Me-4)2, gives the tungstacycle [W{S(NHC6H4Me-4)N(C6H4ME-4)C(0)}(CO)2(η-C5H5)]. A comprehensive mechanism is discussed. Show more
