Dehalosilylation Reactions Involving E(SiMe3)3 and Ph2InCl. Synthesis and Molecular Structures of (Ph2InE(SiMe3)2) 2(E = P or As)

Abstract

Combining P(SiMe3)3 or As(SiMe3)3 With Ph2InCl in a 1:1 mole ratio results in the elimination of Me3SiCl via a dehalosilylation reaction to yield Ph2InP(SiMe3)22 (I) and Ph2lnAs(SiMe3)22 (II), respectively. Both I and H crystallize in the monoclinic system but they are not isomorphous. Crystals of compound I belong to space group P2 sub one/c a = 10.691(1), b = 19.821(2), c = 11.512(1) A, beta = 113.34(1) deg, V = 2239.8(8) A 3, and Dcalc. = 1.324 g cm-3 for Z = 2. Compound II crystallizes in space group P2 sub one/n a = 16.248(1), beta = 20.285(1), c = 13.887(1) A, b = 90.12(1) deg, V = 4577.0(8) A3, and Dcalc. = 1.423 g cm-3 for Z = 4. Full-matrix least-squares refinement based on 2765 (1) and 3625 (H) reflections with I>3Sigma(I), respectively, converged at R = 0.038 (R, = 0.050) for I and R = 0.040 (Rw = 0.048) for 11. The (InP)2 core of dimer I is planar whereas in dimer 11 the (InAs)2 ring is slightly puckered.
