✦ Synopsis

0 NMR spectra of 1,3-dioxa-2-silacyclooctanes have been studied. The 1 7 0 NMR signal of derivatives existing in the crown conformation is shifted downfield by 7-10 ppm relative to derivatives existing predominantly in conformations belonging to the boat-chair family. This shift is assumed to be due to the anomeric effect in 1,3-dioxa-2-silacyclooctanes.
