Synthesis, characterization and reactivity of arene ruthenium compounds based on 2,2?-dipyridylamine and di-2-pyridylbenzylamine and their applications in catalytic hydrogen transfer of ketones
The synthesis and characterization of cationic arene ruthenium compounds [(eta6-p-iPrC6H4Me) RuCl(kappa2-dpa)]BF4 (1), [(eta6-C 6H6)RuCl(kappa2-dpa)]BF4 (2), [(eta6-p-iPrC6H4Me)- RuCl(kappa2-dpb)]BF4 (3), [(eta6-p- iPrC6H4Me)RuCl(kappa2-dpb)]PF 6.CH3OH (4) and [(eta6-C6H 6)-RuCl(kappa2-dpb)]PF6 (5) (arene = C 6H6 or p-iPrC6H4Me; dpa = 2,2?-dipyridylamine and dpb = di-2-pyridylbenzylamine) have been described. Reactions of the representative compounds 1 and 3 with NaN 3, NaCN, and NH4SCN afforded substitution products [(eta6-p-iPrC6H4Me)- Ru(kappa2-dpa)(N3)]BF4 (6), [(eta6-p-iPrC6H4Me) Ru(kappa2-dpa)(CN)]BF4 (7), [(eta6-p- iPrC6H4Me)-Ru(kappa2-dpa)(NCS)] BF4 (8), [(eta6-p-iPrC6H 4Me)Ru(kappa2-dpb)(N3)]BF4 (9), [(eta6-p-iPrC6H4Me)- Ru(kappa2-dpb)(CN)]BF4 (10) and [(eta6-p- iPrC6H4Me)Ru(kappa2-dpb)(NCS)] BF4 (11). The compounds under investigation have been characterized by elemental analyses, spectroscopic and electrochemical studies. Molecular structures of 1, 3, 4 and 5 have been determined crystallographically. The compounds 1-3 and 5 exhibited moderate catalytic activity in the reduction of ketones into corresponding alcohol in absence of a base.
