New P-N cage compounds generated by small-molecule activation

Abstract

The isolation of new small-cage compounds consisting exclusively of Group 15 elements was achieved by exploiting the reactivity of diphosphadiazanediyls. These biradicaloids were used to activate small molecules containing double bonds, such as diazenes and in situ generated diphosphenes, leading to the formation of hexapnicta-[2.1.1]bicyclohexanes.

Keywords: biradicaloids; cage compounds; diphosphenes; phosphorous heterocycles; trapping.
