R. Yanagi et al., SEPARATION OF SILYLATED OXIME ISOMERS BY HIGH-RESOLUTION GAS-CHROMATOGRAPHY, Bulletin of the Chemical Society of Japan, 67(6), 1994, pp. 1740-1742
The stereoisomers of 2-butanone O-trimethylsilyloxime were observed as
separate peaks, the intensity ratio being 1:3, by high resolution GC
equipped with a capillary column. The peak with intensity 3 was assign
ed to the Z isomer of oxime bond and the intensity ratio corresponded
to the stereoisomer ratio of 2-butanone oxime. Silanes including plura
l oxime groups also gave separate stereoisomer peaks corresponding to
the isomer ratio of 2-butanone oxime.
