Abstract
Lithio-2,6-dibromo-3,5-difluoropyridine (2), readily prepared from 2,4,6-tribromo-3,5 difluoropyridine 1, reacts with a range of electrophiles to give various functionalised pyridine derivatives. A subsequent X-ray crystallographic study of 2,6-dibromo-3,5-difluoro(4-pyridyl) methylphenyl ketone 3e shows an unusual solid state lattice packing arrangement.
