The reaction between trihaloisocyanuric acids and alkynes in the presence of acetic acid provides an efficient methodology for preparation of β-haloenol acetates in yields ranging from 34 to 94%, depending on the halogen and alkynes used. This methodology provides an alternative to typical procedures, which usually employ metal catalysis and are limited to terminal alkynes.
三卤代异氰脲酸和炔烃在乙酸存在下的反应提供了一种有效的方法来制备 β-卤代烯醇乙酸酯,收率范围为 34% 至 94%,具体取决于所使用的卤素和炔烃。这种方法提供了典型程序的替代方法,典型程序通常使用金属催化并且仅限于末端炔烃。
