†
Abstract
The reaction of N,N-dimethyl-1-naphthylamine with )2 shows a twist angle between the naphthyl-rings and the Li–Cipso–Li plane of ca. 38°. The magnitude of the 1J(13C,7Li) coupling constant as well as the line splitting pattern of the lithiated carbon atom in the 13C spectrum (THF-d8) demonstrate the existence of a dimeric species at −90 °C in solution. A previously published single crystal X-ray structure of dimeric
