in pentane byproducts: H2, KCl, C(CH3)4; under Ar, a tube charged with complex in C5H12 was connected to a flaskcontaining ClP(C6H5)2 in C5H12, the soln. of ligand was cooled to -45°C, then combined, the mixt. was warmed to 25°C and stirred for 2 d; the mixt. was filtered, the C5H12 was removed under vac., KCl was isolated; the pentane-sol. solid was sublimed at 90-115°C giving the adduct; the residue was recrystd. from C5H12 at -30°C leading to the ((CH3)3CCH2)2InP(C6H5)2;

in pentane byproducts: H2, (Me3CCH2)P(i-Pr)2, KCl; under Ar, standard vac. line techniques; pentane solns. of ClP(i-Pr)2 and In compd. (molar ratio 1:1) cooled to -78°C; combined; warmed slowly to room temp.; stirred for 2 d; pentane sol. products sepd. from ppt. by extn. (8 times); solvent removed by vac. distn. at 0°C; mixt. of three In compds. obtained; P2(i-Pr)4 adduct crystd. at room temp. in drybox; detd. by (1)H and (31)P NMR spectroscopy;

in benzene-d6 byproducts: H2; under Ar, standard vac. line techniques, in NMR tube; mixt. of (Me3CCH2)P(i-Pr)2, In(CH2CMe3)2Cl and K-In compd. (molar ratio 1:1:1) degassed at-196°C in vac.; benzene-d6 added by vac. dictn.; sealed under va c.; warmed to room temp.; 1 d; not isolated; detd. by (1)H and (31)P NMR spectroscopy;

in benzene-d6 under Ar, standard vac. line techniques; In compd. and ClP(i-Pr)2 (molarratio 1.07:1) combined under vac. in benzene-d6; stirred for 18 h; comb ined with benzene-d6 soln. of K-In compd. (1 equiv.) at ambient temp.; stirred for 15 min; not isolated; detd. by (1)H and (31)P NMR spectroscopy;
