Gas chromatographic assay for the new antitumor agent pyrazine-2-diazohydroxide (diazohydroxide) and its stability in buffer, blood and plasma.

T J Wilke et al.

Journal of chromatography, 383(1), 77-83 (1986-11-28)

Diazohydroxide is a new antitumor agent being considered for clinical trial. A sensitive and specific assay for diazohydroxide in physiological media, plasma and blood has been developed based on conversion of diazohydroxide to 2-chloropyrazine in the presence of strong hydrochloric

Cobalt-catalyzed cross-coupling between in situ prepared arylzinc halides and 2-chloropyrimidine or 2-chloropyrazine.

Jeanne-Marie Bégouin et al.

The Journal of organic chemistry, 74(8), 3221-3224 (2009-03-25)

A cobalt-catalyzed cross-coupling of aryl halides with 2-chloropyrimidines or 2-chloropyrazines is reported in satisfactory to high yields. The key step of this procedure is the formation of aromatic organozinc reagents and their coupling with 2-chlorodiazines using the same cobalt halide
