 Abstract    The reaction of K2(PMe)4 • 2 THF with eis-1,2-dichloroethylene yields the hitherto unknown cyclocarbaphosphanes 1,2,3-trimethyl-1,2,3-triphosphole, (PMe)3C2H2 (1), and 2,3,4,6,7,8-hexamethyl-2,3,4,6,7,8-hexaphosphabicyclo[3,3,0]octane, (PMe)6C2H2 (2). Besides, (PMe)s, (PMe)4CH2, (PMe)3C2Hi, and the new six-membered heterocycle (PMe)2(C2H2)2 are formed. The cyclocarbaphosphanes 1 and 2 were characterized by elemental analysis, mass, IR, Raman, and NMR spectra. For the bicyclic compound 2 two diastereomers were obtained and separated. They differ in the position of the methine hydrogens and of the methyl substituents (eis-2 and trans-2). Compound 2 is also produced in the reaction of K2(PMe)4 • 2 THF with £rans-l,2-dichloroethylene whereas with 1,1,2,2- tetrachloroethane mainly (PMe)s is formed. In 1 and in each of thefive-memberedrings of cis-2 and trans-2 the methyl substituents at adjacent phosphorus atoms are situated on opposite sides of the ring.
