1: pentane 2: benzene-d6 View Scheme

in pentane byproducts: P(CH2C(CH3)3)(C6H5)2; under Ar, a C5H12 soln. of PCl(C6H5)2 was added to a C5H12 soln. of In(CH2C(CH3)3)3 at -78°C, the mixt. was warmed to 25°C and stirred overnight; C5H12 was removed under vac. while holding the mixt. at -30°C, the complex was crystd. from C5H12 at -20°C to -30°C and isolated by filtration, purified by vac. distn.;

in benzene stirred, room temp.; not isolated, 1H NMR;

in benzene-d6 byproducts: (Me3CCH2)P(i-Pr)2; under Ar, standard vac. line techniques, in NMR tube; benzene-d6 soln. of ClP(i-Pr)2 added to soln. of In compd. (molar ratio 1:1); evacuated; degassed at -196°C in vac.; sealed; 1 d; not isolated; detd. by (1)H and (31)P NMR spectroscopy;

in benzene The mixt. of reagents in benzene was kept at 60°C for 3 d;; evapd., washed with benzene, pentane at -78°C;;
