摘要

Bis (4, 5-dimethyl-2-pyridyl)-, bis (5-methyl-2-pyridyl)-and bis (4-methyl-2-pyridyl) diselenide have been synthesized directly from 3, 4-lutidine (1a), 3-picoline (1b) and 4-picoline (1c) respectively via BF3 aided lithiation reaction. The lithiation of 3, 4-lutidinium-, 3-and 4- picolinium-BF3 adduct (2a/2b/2c) gives the corresponding carbanion (3a/3b/3c) which on subjecting to selenium insertion reaction followed by aerial oxidation affords the related ...
