Ot. Beachley et al., USE OF ME2GA(C5H5) TO PREPARE (ME2GAERR')N (E = N, P) AT OR BELOW ROOM-TEMPERATURE AND THE CRYSTAL AND MOLECULAR-STRUCTURE OF [ME2GAP(ME)(PH)]3, Organometallics, 12(5), 1993, pp. 1976-1980
The organogallium compound, Me2Ga(C5H5) has been observed to react at
room temperature or below with primary and secondary amines and phosph
ines to form [Me2GaNH273, [Me2GaN(H)(Me)]3, [Me2GaN(H)-(t-Bu)]2, [Me2G
aN(H)(C6H11)]2, [Me2GaNEt2]2, [Me2-GaN(Me)(C6H11)]2, [Me2GaN(Me)(Ph)]2
, [Me2GaN-(Et)(Ph)]2, [Me2GaP(C6H11)2]2, [Me2GaP(Me)(Ph)]3, or [Me2GaP
Ph2]2 and cyclopentadiene. All new compounds have been fully character
ized by their melting points, partial elemental analyses (C and H), H-
1 NMR, P-31 NMR (as appropriate), and IR spectroscopic data, and cryos
copic molecular weight studies. The compound [Me2-GaP(Me)(Ph)]3 crysta
llizes in the trigonal space group R3 with a = 16.526(5) angstrom, c =
10.242(2) angstrom, V = 2421(1) angstrom3, and Z = 3 (trimeric molecu
les). The molecule contains a Ga3P3 ring in the chair conformation wit
h phenylgroups inaxial positions. The Ga-P distances range from 2.407(
4) to 2.413(6) angstrom.
