Reactions of 2,5-dilithiated 1-methylpyrrole (1a) with the aryloxy-boryl derivative 2e. Reacting monolithiated 1methyl-and 1-benzylpyrroles with Cl 2 BNiPr 2 yields the di(2-ClB(NR 2 ) 2 lead to the novel 2,5-diboryl-1-methylpyrroles 2a and 2b. Accordingly, 2,5-diboryl-1-benzylpyrrole 2d is pyrrolyl
