(Chemical Equation Presented) Good old copperl A new general procedure to couple aliphatic and aromatic Grignard reagents with alkynyl halides under copper catalysis is described (see scheme; NMP=N-methylpyrrolidinone). The reaction is chemoselective and allows preparation of a vast array of simple and functionalized internal alkynes in high yields.
Synthesis and Chemistry of 1,3-Diazabiphenylenes
Bakthavachalam, Venkatesalu,d'Alarcao, Marc,Leonard, Nelson J.
, p. 289 - 295 (2007/10/02)
Two independent syntheses of the 1,3-diazabiphenylene ring system have been developed.The first of these involves thermal extrusion of nitrogen from a condensed pyridazine precursor, and the second utilizes a diethynylpyrimidine in a cobalt-catalyzed co-o
