The reaction of (Me3Si)2CHMCl2 (M = As or Sb) with (2,4,6-But3C6H2)PH2 in the presence of 1,5-diazabicycloundec-5-ene affords the double-bonded compounds, (2,4,6-But3C6H2)P=MCH(SiMe3)2 (M = As or Sb).

The syntheses of the symmetrical diphosphene (Me3Si)3CP=PC(SiMe3)3 (2), the unsymmetrical diphosphenes [2,4,6-(t-Bu)3C6H2]P=PC(SiMe3) 3 (5) and [2,4,6-(t-Bu)3C6H2]P=PCH(SiMe3) 2 (7), the phosphaarsene [2,4,6-(t-Bu)3C6H2]P=AsCH(SiMe 3)2 (12), the phosphastibene [2,4,6-(t-Bu)3C6H2]P=SbCH(SiMe 3)2 (14), and the diarsene [2,4,6-(t-Bu)3C6H2] As=AsCH(SiMe3)2 (18) are described. X-ray diffraction studies have been performed on 2, 12, and 18. Diphosphene 2 crystallizes in space group P1 (No. 2) with a = 15.629 (7) ?, b = 9.155 (5) ?, c = 12.486 (6) ?, α = 91.58 (4)°, β = 111.42 (5)°, and γ = 90.02 (4)°. Phosphaarsene 12 crystallizes in space group P1 (No. 2) with a = 9.991 (4) ?, b = 10.452 (9) ?, c = 15.140 (15) ?, α = 89.72 (7)°, β = 85.03 (5)°, and γ = 77.72 (5)°. Diarsene 18 crystallizes in space group P1 (No. 2) with a = 9.955 (9) ?, b = 10.393 (7) ?, c = 15.159 (5) ?, α = 89.56 (4)°, β = 85.39 (6)°, and γ = 78.31 (9)°. The nature of the bonding in these and related double-bonded compounds is discussed with use of the available molecular structural and electronic spectral information. An extensive compilation of 31P NMR spectroscopic data is presented and discussed.
