Radical reactions in an X-ray irradiated single crystal of diphosphene: an ESR study

  • 1. Geneva Univ. (Switzerland). Dept. de Chimie Physique

Description

Two phosphinyl radicals are identified in an X-ray irradiated single crystal of diphosphene. The result from the formation of a five-membered ring containing a phosphorus atom and from the addition of a H atom on the P = P bond respectively. A scission of the radical's P-P bond occurs when the temperature is increased and gives rise to new phosphinyl radicals

Abstract (French)

L'etude RPE d'un monocristal de ArP = PAr irradie aux rayons X permet d'identifier plusieurs radicaux de type phosphinyl. Ceux-ci resultent d'une cyclisation de la molecule qui incorpore un atome de phosphore dans un cycle pentagonal ou de l'addition d'un H· sur l'un des deux atomes de phosphore. Une augmentation de la temperature rompt la liaison P-P presente dans ces radicaux et conduit a de nouvelles especes phosphinyles
