- Reaction of KIn(CH2CMe3)3H with chlorodiphenylphosphine
-
The reaction between KIn(CH2CMe3)3H and ClPPh2 in pentane or benzene produces significant yields of two indium-phosphorus compounds, (Me3CCH2)2-InPPh2 and (Me3CCH2)3In·P(CH2CMe3)2. This unexpected adduct incorporates a neopentyl group that was originally a substituent on the indium reagent. The other products of the reaction are CMe4, H2, and KCl. The formation of all products is explained by a set of experimentally verified reactions.

- SYNTHESIS AND CHARACTERIZATION OF AMPHOTERIC LIGANDS INCLUDING THE CRYSTAL AND MOLECULAR STRUCTURE OF 2
-
The new amphoteric ligands (Me3SiCH2)2GaPPh2, (Me3SiCH2)2InPPh2, and (Me3CCH2)2InPPh2 have been prepared and characterized by elemental analyses, cryoscopic molecular weight measurements and 1H NMR, 31P NMR and IR spectroscopic data.An X-ray structural study was carried out to define the nature of 2 in the solid state.The compounds were prepared either by a thermolysis reaction between the group 13 metal trialkyl and PPh2H or by a metathetical reaction between the dialkylmetal halide and KPPh2.Cryoscopic molecular weight measurements and 31P NMR spectroscopic data demonstrate that the new compounds exist as monomer-dimer equilibrium mixtures in benzene solution.The colorless crystal of 2 contains two discrete molecules of the dimer in each unit cell.The compound crystallizes in the triclinic space group P1, with unit cell dimensions of a 10.323(4), b 11.113(5), c 21.509(8) Angstroem, α 83.85(5), β 86.66(6), γ 83.27(5) deg and ρcalcd 1.29 g cm-3.Full matrix least-squares refinement led to a final R value of 0.035 for 3787 observed reflections.The molecule contains four-membered indium-phosphorus rings.
