Chem Commun (Camb). 2009 Apr 7:(13):1745-7. doi: 10.1039/b822732b. Epub 2009 Feb 5.

Abstract

The complexes [Cp*E{W(CO)5}2] (E=P, As; Cp*=C5Me5) react with 1,2-diphosphinobenzene to give 1,2,3-triphosphole and 2-arsa-1,3-diphosphole derivatives as reactive intermediates that dimerise to polycyclic phosphorous and arsenic containing cage compounds.
