title: Synthesis of the (dialkylamino)borate, [Ph(2)B(CH(2)NMe(2))(2)](-), affords access to N-chelated rhodium(I) zwitterions.
abstract: This paper reports the synthesis of the first bis(amino)borate ligand, [Ph(2)B(CH(2)NMe(2))(2)](-), an anionic equivalent of tertiary diamines. Anionic [Ph(2)B(CH(2)NMe(2))(2)] is an excellent bidentate ligand auxiliary and is used to prepare a series of N-chelated, zwitterionic rhodium(I) complexes.
