for palladium-catalyzed oxidative deacetonative coupling of 4-aryl-2-methyl-3-butyn-2-ols with dialkyl H-phosphonates has been developed. This methodology provides a new and practical route to alkynylphosphonates using the inexpensive 4-aryl-2-methyl-3-butyn-2-ols as the alkyne sources. This reaction could also be performed with aryl bromides, 2-methyl-3-butyne-2-ol and dialkyl H-phosphonates using
已经开发出一种有效的和普遍适用的方案,用于4-芳基-2-甲基-3-丁炔-2-醇与H-膦酸二烷基酯的钯催化的氧化脱乙酰化偶联。这种方法为廉价的4-芳基-2-甲基-3-丁炔-2-醇作为炔烃来源提供了一条新的实用路线,以制备炔基膦酸酯。该反应也可以使用廉价的2-甲基-3-丁炔-2-醇作为炔烃源,与芳基溴化物,2-甲基-3-丁炔-2-醇和H-膦酸二烷基酯一起进行。
