A series of palladium thiolate complexes of the [Pd(Ph2PC 6H4-2-(CH2NMe2))(SR F)2] type have been synthesized in good yields by metathetical reactions of [Pd(Ph2PC6H4-2- (CH2NMe2))Cl2] (1) with [Pb(SR F)2], (SRF = S-C6F5, S-C6F4-4-H, S-C6H4-2-CF3, S-C6H4-4-F, S-C6H4-2-F) and their crystal structures determined. Heck coupling reactions were carried out using [Pd(Ph2PC6H4-2-(CH2NMe 2))(SRF)2], SRF = S-C 6F5 (2), S-C6F4-4-H (3), S-C 6H4-2-CF3 (4), S-C6H4-4-F (5), S-C6H4-2-F (6) complexes as catalysts in order to examine the effect of the thiolates in the reaction of bromobenzene and styrene. The results obtained indicate that the less electron-withdrawing substituents on the thiolate moiety may favor higher yields in the Pd catalyzed Heck reaction using [Pd(Ph2PC6H4-2-(CH2NMe 2))(SRF)2] as catalysts.
