Akita, Yasuo,Inoue, Akira,Ohta, Akihiro
, p. 1447 - 1458 (2007/10/02)
Various chloropyrazines were subjected to cross-coupling reaction with acetylenes, such as phenylacetylene, 1-hexyne and propargyl alcohol, in the presence of palladium catalysts, to give the corresponding coupling products in good yields.It was found, th
