the first microwave-assisted one-pot three-step metal-free [4+2] procedure for the synthesis of 5,6-substituted-3-hydrazinyl-1,2,4-triazines directly from commercially available aromatic and heteroaromatic ketones. Based on literature, a plausible mechanism is postulated. The 3-hydrazinyl-1,2,4-triazine can be isolated or further elaborated to provide highly functionalized hydrazone-derivatives.
在此,我们报告了第一个微波辅助一锅三步无金属[4+2]程序,直接从市售芳族化合物合成5,6-取代-3-肼基-1,2,4-三嗪。杂芳酮。根据文献,假设了一种合理的机制。 3-肼基-1,2,4-三嗪可以被分离或进一步精制以提供高度官能化的腙衍生物。
