Desaintjean, Alexandre,Haupt, Tobias,Bole, Leonie J.,Judge, Neil R.,Hevia, Eva,Knochel, Paul
supporting information, p. 1513 - 1518 (2020/11/30)
Using the bimetallic combination sBu2Mg?2 LiOR (R=2-ethylhexyl) in toluene enables efficient and regioselective Br/Mg exchanges with various dibromo-arenes and -heteroarenes under mild reaction conditions and provides bromo-substituted magnesiu
Preparation and reactions of pyridinyl tellurides

, p. 481 - 484 (2007/10/03)
Tellurium-metal exchange reaction of n-butyl 2-pyridinyl telluride derivatives with n-butyllithium or dilithium dimethylcyanocuprate proceeded smoothly to give the corresponding 2-pyridinylmetal derivatives, which are important intermediates for functionalization of pyridines.
Selective monolithiation of 2,5-dibromopyridine with butyllithium
Wang, Xin,Rabbat, Philippe,O'Shea, Paul,Tillyer, Richard,Grabowski,Reider, Paul J.
, p. 4335 - 4338 (2007/10/03)
Selective monolithiation of 2,5-dibromopyridine at either the 2-position or the 5-position is reported. Solvent and concentration strongly influence the selectivity. Coordinating solvents and higher concentration favor the 5- position while non-coordinati

Kondo, Yoshinori,Shilai, Manabu,Uchiyama, Masanobu,Sakamoto, Takao
, p. 1781 - 1782 (2007/10/03)
Pyridyltellurium derivatives have been prepared from the reaction of halopyridines with lithium butanetellurolate and the tellurium-metal exchange of pyridyltellurium derivatives has been investigated using butyllithium and dilithium dimethylcyanocuprate.
