By using an optically active cobalt complex, N,N′-disalicylidene-(1R,2R)-1,2-cyclohexanediaminatocobalt(II), as a catalyst, optically active methyloxirane was synthesized by the asymmetric elimination of hydrogen chloride with a base from racemic p

The deuterium-decoupled 100 MHz 1H-NMR spectra of 2,3-dideuteromethyloxirane and its polymer prepared with a lattice-disordered zinc dialkoxide were analyzed with consideration of the deuterium isotope effects on proton chemical shifts. The results o

The infrared spectra of diethylcadmium(CdEt2) in a variety of different solvents were measured. The affinity of CdEt2 toward oxygen and sulfur bases was studied by infrared frequency shifts of CdEt2. Linear relationships were observed for the plots o

Optically active chloromethyloxirane was obtained from 1,3-dichloro-2-propanol by a process of asymmetric synthesis. The highest enantiomenc excess (e. e. ) of chloromethyloxirane that could be obtained was 67%, using Co(II) (3,5-Cl,Cl-sal)2(S-CHXDA)
