Abstract

The reaction of Ph2PCl and PhPCl2 with bis(trimethylsilyl)sulfur diimide in the presence of GaCl3 and AlCl3 yields diadducts of the corresponding cyclodiphosph(V)azene: [Ph2PN]2·(GaCl3)2 (1), [Ph2PN]2·(AlCl3)2 (2), and [Ph(Cl)PN]2·(AlCl3)2 (3). This reaction is triggered by Lewis acids, which catalyse the (CH3)3Si-Cl and S8 elimination. The structures of 2 CH2Cl2, 2 CH2Cl2 and 3 were determined by single crystal X-ray studies (1: triclinic, equation image, a = 9.679(2) Å, b = 9.863(2) Å, c = 11.366(2) Å, α = 113.55(3)°; β = 99.59(3)°; γ = 106.67(3)°; V = 902.8(3) Å3, Z = 1; 2: triclinic, equation image, a = 9.639(2) Å, b = 9.804(2) Å, c = 11.321(2) Å, α = 113.71(3)°; β = 99.44(3)°; γ = 106.70(3)°; V = 889.3(3) Å3, Z = 1; 3: orthorhombic, Pbca, a = 14.853(3) Å, b = 9.261(2) Å, c = 16.631(3) Å, V = 2287.7(8) Å3, Z = 4.
