Abstract
Abstract Reaction of [PdCl2(DPPE)] (DPPE = Ph2PCH2CH2PPh2) with N-cyanoacetylurethane, NCCH2NHCO2Et, and silver(I) oxide gave the four-membered ring palladalactam complex [P d{CH(CN)C(O)N (CO2Et)}(DPPE)] in high yield. In contrast, reaction of [PdCl2(PPh3)2] with N-cyanoacetylurethane and silver(I) oxide gave the monodentate amide complex trans-[PdCl{EtO2CNC(O)CH2CN}(PPh3)2] in high yield. The amide complex was characterized by multinuclear NMR spectroscopy and by a single-crystal X-ray diffraction study. The plane of the N-bonded cyanoacetylurethane ligand is virtually perpendicular to the square-plane of the palladium coordination sphere.
