On the synthesis of siloxanes. XXIV. Nucleophilic substitution reactions of 2-functional 1,3-dioxa-2,4,7-trisilacycloheptanes and 1,3-dioxa-2,4,8-trisilacyclooctanes

2-Hydrogen-1,3-dioxa-2,4,7-trisilacycloheptanes and 2-hydrogen-1,3-dioxa-2,4,8-trisilacyclooctanes, each as a mixture of three configurational isomers, were synthesized and halogenated with chlorine and bromine in the presence of pyridine. The stereochemi

On the synthesis of siloxanes. XXIII. Synthesis and spectroscopic characterization of 2-functional 1,3-dioxa-2,4,7-trisilacycloheptanes

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.Keywords: Cyclosiloxanes; Synthesis; Spectroscopic characterization
