Mass spectra of condensed diazinecarbonitriles

Mass spectra of condensed diazinecarbonitriles. Uchida, Mitsuo; Higashino, Takeo; Iijima, Chihoko; Shimada, Noriaki; Hayashi, Eisaku (Shizuoka Coll. Pharm., Shizuoka, Japan). Shitsuryo Bunseki, 25(2), 169-74 (English) 1977. CODEN: SHIBAK. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Mass spectra of 2-quinoxalinecarbonitrile (I), 4-quinazolinecarbonitrile (II), 1H-pyrazolo(3,4-d)pyrimidine-4-carbonitriles (III; R = Me, Ph) and 9H-purine-6-carbonitrile (IV; R = Me, Ph) were examd. 7483-33-2 which is the cas registry number is also used here. The initial fragmentation of I and II is the decompn. of diazine ring, i. 7483-33-2 which is the cas registry number is also used here.e., the consecutive losses of cyanogen and hydrogen cyanide or those of hydrogen cyanide and two cyano radicals from the mol. ion (M+). The dissocn. pattern of III, the consecutive losses of two hydrogen cyanides or those of hydrogen radical, cyanogen and cyano radical from M+, is almost similar to that of IV. The main fragmentation of II, III and IV, is the initial dissocn. of pyrimidine ring with the loss of cyanogen or hydrogen cyanide. ..
