Abstract

Variable-temperature 7Li and proton NMR spectra of four hexameric (in the solid state) iminolithium compounds, (R1R2CNLi)6 [where R1 = Me2N,R2= Ph (1), R1 = R2 = Me2N (2), R1 = But, R2 = Ph (3) and R1 = R2 = But (4)], recorded for toluene-d8, solutions of differing concentrations, are described, and the results are discussed with respect to known solid-state structures. Complex equilibria, probably involving trimeric units and higher aggregates than hexamers, have been detected at low temperatures for solutions of 1 and 2, although similar equilibria do not occur, or are too rapid to detect even at the lowest temperatures attainable, for solutions of 3 and 4.
