Abstract
A procedure is described for the separation and identification of cis- and trans-2,2,4,4-tetramethyl-1,3-cyclobutanediol. The separation of the isomeric diols was achieved by gas chromatography on an HP-1 capillary column under optimized conditions. The identification of the isomers was carried out through the mass spectrometric analysis of silyl derivatives prepared by using silylating agents of different steric demands. Striking reactivity differences of the isomers resulted in selective derivatization, permitting the unequivocal identification of the isomers. The results were supported by the analysis of authentic samples.
