31886-58-5, (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine is a chiral-nitrogen-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
15.4 ml of a cyclohexane solution of s-butyllithium (1.3 M, 22 mmol) are added to a solution of 5.14 g (20 mmol) of (R)-N, N-dimethyl-1 -ferrocenylethylamine [(R)-ugi- amine] in 30 ml of t-butyl methyl ether (TBME) at <20C over a period of 10 minutes. The mixture is then heated to 00C while stirring and maintained at this temperature for 1.5 hours. It is then cooled to <60C and 3.0 ml (20 mmol) of dichlorocyclohexyl- phosphine are added over a period of 10 minutes. After stirring at -78C for30 minutes, the mixture is allowed to warm slowly to room temperature and is stirred at this temperature for 1.5 hours.
31886-58-5 (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine 16212257, achiral-nitrogen-ligands compound, is more and more widely used in various.
