Dilithiocarborane, B10H10C2Li2, was allowed to react with chlorophosphines containing one, two, and three chlorine atoms. (C6H5)2PCl and C6H5PCl2 gave the expected disubstituted compounds, B10H10C2[P(C6H5) 2]2 and B10H10C2(C6H 5P·Cl)2, respectively. B10H10C2Li2 and PCl3, however, formed a compound having two phosphorus atoms and two carborane nuclei in a six-membered ring. This unique ring system also arose from the reaction of B10H10C2Li2 with B10H10C2(C6H 5P·Cl)2. Subsequent reactions of such molecules with ammonia and NaN3 are described. The cyclic bis-azide, (B10H10C2P·N3)2. and p-[(C6H5)2P]2C6H 4 reacted to form a PNP bonded oligomer.
