 Title    Beiträge zur Chemie des Phosphors, 85 [1, 2] Synthese und Eigenschaften der Diphosphirane (f-BuP)2CMe2 und (£-BuP)2CH2 Contributions to the Chemistry of Phosphorus, 85 [1, 2] Synthesis and Properties of the Diphosphiranes (£-BuP)2CMe2 and (£-BuP)2CH2  
 Abstract    The first three-membered P2C heterocycles, l,2-di-Zer£-butyl-3,3-dimethyl-diphos-phirane, (M3uP)2CMe2 (1), and l,2-di-£er£-butyl-diphosphirane, (Z-BuP)2CH2 (2), were synthesized by [2 + 1] cyclocondensation reactions of K(i-Bu)P-P(<-Bu)K with 2,2-di-chloropropane and dichloromethane, respectively. Both compounds could be isolated in a pure state by vacuum distillation. Whereas 1 is surprisingly stable under inert condi-tions, 2 dimerizes already at room temperature to form the six-membered cyclocarba-phosphane l,2,4,5-tetra-£er^butyl-cyclo-3,6-dicarba-l,2,4,5-tetraphosphane, (£-BUP)4(CH2)2 (3). The diphosphiranes 1 and 2 were characterized by elemental analysis, osmometric molecular mass determination, mass, NMR, and IR spectra. The <-butyl groups are situated on opposite sides of the P2C ring, whereas the dimeric compound 3 possesses an "all-trans'' configuration of the organyl substituents.

 Title    Beiträge zur Chemie des Phosphors, 84 [1] 1.2.3-Trimethyl  
 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.
