The reaction of 5-amino-3-Q-1H-1,2,4-triazoles 1 with aliphatic, aromatic and cyclic 1,3-diketones, 1,4-diketones, and different linear and non linear triketones was studied. It was proved that in case of unsym-metrical aliphatic 1,3-diketones the regiochemical outcome of the reaction was influenced by steric factors. In case of triacetylmethane and 3-(4-chlorobenzyl)-2,4-pentanedione the splitting
研究了5-氨基-3-Q-1 H -1,2,4-三唑1与脂肪族,芳香族和环状1,3-二酮,1,4-二酮以及不同的线性和非线性三酮的反应。已经证明,在非对称脂族1,3-二酮的情况下,反应的区域化学结果受空间因素影响。在三乙酰甲烷和3-(4-氯苄基)-2,4-戊二酮的情况下,在反应过程中观察到一个乙酰基从反应物中分裂出来。线性三酮,即2,4,6-三氧庚烷反应为简单的1,3-二酮。
