  In the treatment of 6-benzoyl-6, 7-dihydro-3-phenyl-3H-1, 2, 3-triazolo[4, 5-d]pyrimidine-7-carbonitrile (1, triazolo-pyrimidine Reissert compound) and 6-benzoyl-6, 7-dihydro-5-methyl-3-phenyl-3H-1, 2, 3-triazolo[4, 5-d]pyrimidine-7-carbonitrile (2, 5-methyltriazolopyrimidine Reissert compound) with an acid, the ring fission of the pyrimidine ring proceeded to give the triazole derivatives (3-7). Alkaline hydrolysis of 2 and 1 gave 5-metyl-3-phenyl- (10) and 3-phenyl-3H-1, 2, 3-triazolo[4, 5-d]pyrimidines (9), respectively. The anions, generated from 1 and 2 with sodium hydride (NaH), underwent aromatization to give the 3H-1, 2, 3-triazolo[4, 5-d]pyrimidine-7-carbonitriles (12 and 14). Compounds 1 and 2 reacted with arylaldehydes in the presence of NaH to give corresponding 3H-1, 2, 3-triazolo[4, 5-d]pyrimidin-7-ylmethyl benzoates (15 and 17).

  4-(α-Benzyl-α-hydroxybenzyl)quinazoline (4a) underwent retro-benzoin condensation catalyzed by cyanide ion to give deoxybenzoin (2a) and quinazoline (5a). Similarly, several nitrogen-containing heteroarenes (4, 9, 12, 16-19) having an α-hydroxybenzyl group at the α-position of the nitrogen underwent retro-benzoin type condensation to afford ketones (2) and heteroarenes (5). However, similar reaction of pyrazolopyrimidines (13, 14, 15) having an α-benzyl-α-hydroxybenzyl group resulted in benzyl migration, giving benzylpyrazolopyrimidines (8) and arenecarbaldehydes (3). Tetrabutylammonium cyanide (11, Bu4NCN) was a more effective cyanide ion donor than KCN (10). The retro-benzoin condensation was applied to the synthesis of 2-substituted quinazolines (38) from 2-chloro-4-aroylquinazolines (34), using the aroyl group as a protecting and electron-withdrawing group.

  4-(α-苄基-α-羟基苄基)喹唑啉(4a)在氰离子催化下经历逆苯偶姻缩合反应，生成脱氧苯偶姻(2a)和喹唑啉(5a)。同样，多个含氮杂环芳烃(4, 9, 12, 16-19)在其氮原子的α位上具有α-羟基苄基的结构，也经历逆苯偶姻型缩合反应，生成了酮(2)和杂环芳烃(5)。然而，具有α-苄基-α-羟基苄基结构的吡唑嘧啶(13, 14, 15)在类似的反应中引发了苄基迁移，生成了苄基吡唑嘧啶(8)和芳烃羰醛(3)。四丁基铵氰(11, Bu4NCN)比KCN(10)更有效地作为氰离子的供体。逆苯偶姻缩合反应被应用于从2-氯-4-芳酰基喹唑啉(34)合成2-取代喹唑啉(38)，使用芳酰基作为保护和电子 withdrawing 基团。
