obtained. The rate of hydrolysis of these ethers ramged from a few hours to several days. A theoretical investigation demonstrated that the acidic release of alcohols from triazole derivatives proceeds first by protonation of the triazole ring followed by proton transfer from the triazole ring to the carbonyl group of the carbonates or to the oxygen atom of the ether derivatives. The rate of the decomposition
新的基于三唑基的碳酸酯和醚已被研究作为弱酸性条件下潜在的醇释放系统。三唑基碳酸酯由于其明显的不稳定性而无法制备,而成功地获得了醚。这些醚的水解速度从几小时到几天不等。一项理论研究表明,醇从三唑衍生物的酸性释放首先通过三唑环的质子化进行,然后质子从三唑环转移到碳酸酯的羰基或醚衍生物的氧原子。分解反应的速率取决于中间 C-NH+/E-NH+ 结构中 N3–H...O 氢键的长度和三唑碳正离子的稳定性,
