Three pendant benzamidines, [Ph–C(NC6H5)–NH(E)}] [E = –(CH2)2SMe (1); –(CH2)2StBu (2); –o-C6H4SMe (3)], are described. Reactions of 1, 2 or 3 with one molar equivalent of Pd(OAc)2 in CH2Cl2 give the palladacyclic complexes, [Ph–C–NH(η1-C6H4)}N(E)}]Pd(OAc) [E = –(CH2)2SMe (4); –(CH2)2StBu (5); –o-C6H4SMe (6)], as mononuclear palladium complexes respectively. A minor product described as 5′, [Ph–C–N(C6H5)}–N(CH2)2StBu}]Pd(OAc)}2, was isolated as benzamidinate-bridged dinuclear palladium complex upon recrystallizing from Et2O/hexane solution. Treatment of 1, 2 or 3 with one molar equivalent of PdCl2 in the presence of NEt3 in CH2Cl2 gives the palladacyclic complexes, [Ph–C–NH(η1-C6H4)}N(E)}]PdCl [E = –(CH2)2SMe (7); –(CH2)2StBu (8); –o-C6H4SMe (9)], as mononuclear palladium complexes respectively. The crystal and molecular structures are reported for compounds 5, 5′ and 6–8. The application of these palladacyclic complexes to the Suzuki and Heck coupling reactions was examined.
