, p. 265 - 273 (2007/10/03)
A preparation of Grignard derivatives of diazines is described using a halogen magnesium exchange reaction. This convenient method allows the functionalization of these rings at 0°C or even room temperature.
A New Route to 2,3-Disubstituted Pyrazines; Regioselective Metalation of Chloropyrazine
Turck, A.,Mojovic, L.,Queguiner, G.
, p. 881 - 884 (2007/10/02)
Chloropyrazine is regioselectively metalated by lithium amides in tetrahydrofuran to give 3-chloro-2-lithiopyrazine.The reaction of this lithio derivative with electrophiles can either be performed in situ (with the electrophile, e.g., chlorotrimethylsila
