Oxidative magnesiation of halogenopyridines was carried out using active magnesium prepared by the reduction of magnesium chloride, to give pyridinylmagnesium halides, which were treated with electrophiles to afford the corresponding pyridine derivatives.

The oxidative magnesiation of nitrogen-containing π-deficient halogenoheteroaromatics using active magnesium was accomplished. Both magnesiation followed by addition of a carbonyl compound (Grignard reaction) and magnesiation in the presence of a carbonyl compound (Barbier reaction) were carried out to afford the corresponding product. Especially, the latter method enabled fused halogenodiazines such as 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine or 2-chloroquinoxaline to magnesiate at a mild temperature (-20 to 30 °C).
