7Li,31P Shift correlation. Application to the structural assignment of benzyllithium complexes of N-methyl-N-benzylphosphinamide.
A correlation experiment between (7)Li and (31)P nuclei through scalar coupling is described for the first time. The utility of the method is demonstrated by identifying the species formed in the benzylic lithiation of N-benzyl-N-methyldiphenylphosphinamide in Et(2)O solution.
