A new system for the selective synthesis of bisdimethylamine derivatives usingdiols and aqueous dimethylamine as the starting materials was developed. An iridium complex bearing an N-heterocyclic carbene ligand was used as the catalyst, and the reaction proceeded based on the borrowing hydrogen strategy in an aqueousmediumunder mild conditions. Various bisdimethylamine derivatives were obtained

Me2N[CH2]nNMe2(n= 5, 7, or 10) gives binuclear complexes trans-[Pd2Cl4Me2N(CH2)nNMe2}2] in good yield. The crystalstructures of the 16-atom ring (n= 5) and 20-atom ring (n= 7) complexes were determined from 2577 and 1154 diffractometer data, respectively, and were refined to R of 0.034 and 0.057, respectively. They are compared with the structures of trans-[Pd2Cl4But2P(CH2)nPBut2}2](n= 5 or 7). The
