2,2,2-Triphenyl-1,2-oxaphosph(V)olan and -oxa-ars(V)olan

Abstract
2,2,2-Triphenyl-1,2-oxaphosph(V)olan has been prepared from 3-hydroxypropyltriphenylphosphonium iodide, and rearranges at 300° to 3-phenoxypropyldiphenylphosphine. 2,2,2-Triphenyl-1,2-oxa-ars(V)olan has been prepared from the corresponding arsonium salt, and at 160–180° gave triphenylarsine and allyl alcohol. The nuclear magnetic resonance spectra of the title compounds are given.
