Abstrakt: A 1:1 mixture of In(CH2CMe3)3 and HP(i-Pr)2 at room temperature undergoes a very slow hydrocarbon elimination reaction to form [(Me3CCH2)2InP(i-Pr)2]2 and neopentane. The indium phosphide [(Me3CCH2)2InP(i-Pr)2]2 has also been prepared by reacting KIn(CH2CMe3)3H with ClP(i-Pr)2 in pentane. When pentane solutions of these reagents were combined at −78 °C and then maintained at ~20 °C for 2 days, [(Me3CCH2)2InP(i-Pr)2]2, (Me3CCH2)3In·P(H)(i-Pr)2, (Me3CCH2)3In·P2(i-Pr)4, (Me3CCH2)3In·P(CH2CMe3)(i-Pr)2, H2, indium metal, and KCl were observed. The formation of all products is explained by a set of experimentally verified reactions. An X-ray structural study of [(Me3CCH2)2InP(i-Pr)2]2 shows each molecule to have an unusual puckered four-membered In2P2 core.
