Contributions in the Chemistry of Phosphorus, 131. Synthesis and Properties of the Methylenediphosphiranes (t-BuP)2C = CR2 (R = H, Me, 4-ClC6H4)

The first methylenediphoshiranes (diphosphamethylenecyclopropanes) (t-BuP)2C = CH2 (1), (t-BuP)2C = CMe2 (2), and (t-BuP)2C = C(4-ClC6H4)2 (3) were synthesized by cyclocondensation of K(t-Bu)P - P(t-Bu)K with the corresponding 1,1-dichloroolefins.The homocyclophosphanes (t-BuP)n (n = 4,3) and in the case of 1 mainly H(t-Bu)P - P(t-Bu)H are formed as by-products.The three-membered heterocycles 2 and 3 could be purely isolated as surprisingly stable compounds.According to an X-ray single-crystal analysis 3 possesses approximately C2 symmetry and exhibits one of the smallest bonding angles φ (P - P - C) = 52.4 deg on a phosphorus atom experimentally proved so far.Along there are canals filled with disordered n-pentane molecules.
