Name is (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine, as a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, and cas is 31886-58-5, its synthesis route is as follows.,31886-58-5
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 2.47 ml (20 mmol) of dichlororopropyl- phosphine are added over a period of 10 mintues. 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.
With the complex challenges of chemical substances, we look forward to future research findings about (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine
