2,4-Di-tert-butyl-6-piperidinophenyl as a sterically and electronically stabilizing group and X-ray analysis of the corresponding diselenoxophosphorane
Abstract
The 2,4-di-tert-butyl-6-(1-piperidino)phenyl group is utilized to stabilize diselenoxophosphorane and the structure determined by X-ray analysis indicates coordination of the nitrogen lone-pair to the P-atom to form a four-membered ring with a remarkably distorted P–C–C bond angle.
