Described here are tandem photoelectrocyclization and [1,5]-hydride shift reactions of heteroaryl-containing bis-aryl cyclohexenone derivatives that give heteroaryl-substituted dihydrophenanthrenes. This Letter demonstrates that electrocyclization intermediates can be trapped with acid when the [1,5]-hydride shift is relatively slow. From a practical perspective, the observation that the acid-mediated reaction gives a divergent stereochemical outcome when compared with the reaction run under neutral conditions makes these transformations powerful.

Studies on pyrazines. 35 [1]. An improved synthesis of bromopyrazines from hydroxypyrazines
Sato, Nobuhiro,Narita, Nobuhiko
, p. 783 - 786 (2007/10/03)
The synthesis of bromopyrazines from hydroxypyrazines was successfully effected by the procedure via trimethylsilyloxypyrazines, the sequence of which proceeds under mild conditions and does not require the isolation of intermediate.
Organozinc derivatives of diazines, metalation of diazines XXIII
Turck, Alain,Plé, Nelly,Leprêtre-Gaquère, Anne,Quéguiner, Guy
, p. 205 - 214 (2007/10/03)
Some organozinc derivatives of diazines have been prepared from lithiated diazines and zinc chloride. They reacted in cross coupling reactions with iodobenzene, 2-bromopyridine and 5-bromopyrimidine. The use of sonication, for the first time in a Negishi reaction, lowered the reaction times significantly and improved the yields.
