摘要: Abstract Reaction of isophthaloyl dichloride with two equivalents benzylamine in the presence Et3N gives N,N′-dibenzyl-1,3-isophthaldiamide which reacts Ph2PCl, n-BuLi at −78 °C to give 1,3-C6H4-{C(O)N(PPh2)CH2Ph}2 (1). 1 [PtCl2(cod)] dichloromethane P,P′,C tridentate bis-chelate [Pt(Cl){1,3-C6H4-{C(O)N(PPh2)CH2Ph}2}] (2), whilst reaction [(C3H5)PdCl]2 thf results [{PdCl(C3H5)}2 {1,3-C6H4-{C(O)N(PPh2)CH2Ph}2}] (3) ligand bridges palladium centres. The X-ray structures 2 and 3 are reported.
