The terdentate ligands bis(2-(diphenylphosphino)ethyl)benzylamine (DPBA) and bis(2-(diphenylarsino)ethyl)benzylamine (DABA) were synthesized and characterized on the basis of their mass spectra and /sup 1/H, /sup 31/P, and /sup 13/C NMR spectra. Some of the complexes of these ligands (L) with ruthenium(II) and ruthenium(III) were prepared by employing various starting materials. The reaction of RuCl/sub 2/(PPh/sub 3/)/sub 3/ with a twofold excess of L in acetone or n-hexane gave the neutral complex (RuCl/sub 2/(PPh/sub 2/)(L)) (L = DPBA or DABA). The reaction of DPBA with RuCl/sub 2/(PPh/sub 3/)/sub 3/ in methanol, however, gave the cationic complex (RuCl(DPBA)/sub 2/)Cl. Neutral monomeric complexes of the type (RuCl/sub 3/(L)) were obtained by the reaction of L with RuCl/sub 3/(AsPh/sub 3/)/sub 2/MeOH, in acetone. The cationic complex (RuCl(DPBA)/sub 2/)Cl/sub 2/ was obtained by the reaction of RuCl/sub 3/(AsPh/sub 3/)/sub 2/MeOH with DPBA in methanol. Similar reactions with RuBr/sub 3/(AsPh/sub 3/)/sub 2/MeOH in acetone yielded (RuBr/sub 2/(AsPh/sub 2/)(L))Br(L = DPBA or DABA) and (RuBr/sub 3/(DABA)). The reaction of RuCl/sub 2/(Me/sub 2/SO)/sub 4/ with DPBA and DABA in acetone gave the complexes (RuCl(Me/sub 2/SO)/sub 2/(DPBA))Cl and (RuCl/sub 2/(Me/sub 2/SO)(DABA)), respectively. The reaction of RuCl/sub 3/.3H/sub 2/O with a twofold excess of DPBA and NH/sub 4/PF/sub 6/ in methanol gave the Ru(II) cationic species (Ru(DPBA)/sub 2/)(PF/sub 6/)/sub 2/ whereas DABA yielded the ruthenium(III) cationic complex (RuCl(DABA)/sub 2/)Cl/sub 2/. The results of /sup 1/H and /sup 31/P NMR, EPR, and other spectral data of the complexes are discussed. 35 references, 4 tables.
