A series of 2-functional 1,3-dioxa-2,4,7-trisilacycloheptanes was synthesized and characterized by means of 29Si NMR spectroscopy, gas chromatography, high performance liquid chromatography and gas chromatography-mass spectrometry. The signals were assigned to the various configurational isomers. This assignment was confirmed by independent synthesis of individual isomers. The sequence of the NMR signals of the all-cis and trans-trans isomers required for the determination of stereochemistry was found to be the same as that of the respective cyclotrisiloxanes.
