Abstract
A 1:1:1 reaction of 3-methylpyridine, 1, with LDA and PhCN in the pres ence of PMDETA gives the title complex 6, shown by X-ray crystallograp hy to be the first monomeric iminolithium. The isolation of 6, and of a cyclised product 8 when a 3:10:3 reaction of 1:LDA:PhCN is carried o ut, suggest a mechanism for previously published cyclisation reactions of beta-methylazines.
