Dicarbonylbis[2-(diphenylphosphino)-N,N-dimethyethanamine]-bis-[μ-(2-methyl)-2-propanethiolato]dirhodium and dicarbonylbis[2-(diphenylphosphino)-N,N,N-trimethylethanaminium]-bis-[μ-(2-methyl)-2-propanethiolato]dirhodium tetraphenylborate. Their syntheses, characterization and application as hydrogenation catalyst
摘要:
[Rh(CO)(2)(mu-S-t-Bu)](2) (1) reacts with [Ph(2)PCH(2)CH(2)NMe(3)](+)[BPh(4)](-) (2) as well as with the neutral Ph(2)PCH(2)CH(2)NMe(2) (4) to give the water soluble cationic dinuclear rhodium complex [Rh(CO)(Ph(2)PCH(2)CH(2)NMe(3))(mu-S-t-BU)](2+)(2)[BPh(4)](2-)(2) (3) and the neutral dinuclear complex [Rh(CO)(Ph(2)PCH(2)CH(2)NMe(2))(mu-S-t-Bu)](2) (5), respectively. Both are highly active catalysts for hydrogenation. The NMR spectra of the new compounds and the X-ray crystal structure analysis of 5 are reported and discussed.
