Differential gas–liquid chromatographic behaviour in diastereoisomeric systems. Part III. Symmetrically substituted dichiral ethers, alkoxysiloxanes, and disiloxanes

Abstract

G.l.c. resolution of diastereomers containing an asymmetric silicon atom as alkoxysiloxane was studied and compared with that of similar compounds of the ether and of the disiloxane series. The resolution factors of some diastereomers containing an asymmetric silicon atom are ca. 1·04 and complete separation is achieved on an efficient capillary column coated with Apiezon L.
