The new, stable, penta-alkyl phosphoranes (CF3)3PMe2 and (CF3)2PMe3 are, according to n.m.r. spectral evidence, trigonal bipyramidal molecules, probably non-fluxional, in which CF3 groups are found to be preferentially located in the axial positions.
根据nmr光谱证据,新的稳定的五烷基膦烷(CF 3)3 PMe 2和(CF 3)2 PMe 3是可能是非氟的三角双锥体分子,其中发现CF 3基团是优先位于轴向位置。
