N.m.r. spectroscopic studies of three new tetra-alkylphosphoranes, Me(CF3)3PX (X = F, Cl, OMe), confirm their true phosphoranes character and suggest that the ground state structures observable at low temperatures have a halogen and a CF3(X = F, Cl) or two CF3 groups (X = Me) in the axial positions of a trigonal bipyramidal framework.
Nmr光谱研究了三种新的四烷基磷ora烷Me(CF 3)3 PX(X = F,Cl,OMe),证实了它们的真实磷烷特性,并表明在低温下可观察到的基态结构具有卤素和CF 3。(X = F,Cl)或两个双锥体骨架轴向位置上的两个CF 3基团(X = Me)。
