Rh(I) and Ir(I) dithioether complexes and their application in the hydrogenation of olefins
摘要:
Mononuclear complexes [M(cod)(RS(CH2)(n)SR)]BF4 (M = Rh, Ir; n = 2-4)) were synthesized and characterized. The crystal structure of [Rh(cod){(CH3)(2)CHS(CH2)(4)SCH(CH3)(2)}]BF4 was determined by X-ray diffraction. The iridium complexes are catalytically active precursors in the hydrogenation of olefins. The effect of the length of the backbone between the two sulfur atoms and the group R bonded to sulfur was studied in the hydrogenation of itaconic acid and 1-hexene. (C) 2001 Elsevier Science B.V.

Synthesis of α-Halogeno-Ï-alkylthioalkanes and α,Ï-Bisalkylthioalkanes The reaction of α,Ï-dihalogenated alkanes [X(CH2)nX,,n = 3 - 10]with alkylthiolates affords α-halogeno-Ï-alkylthioalkanes 1 as well as α,Ï-bisalkylthioalkanes 2. Products 1 (40 examples) and 2 (22 examples) are easily isolated in good yields by flash chromatography.
