water-soluble catalyst for the coupling of arylboronic acids with (2-haloallyl)phosphonates and (2-haloallyl)sulfones in water under air was developed. The reaction was performed at 120 °C with arylboronic acids (2 mmol) and (2-haloallyl)phosphonates or sulfones (1 mmol) in the presence of 5 mol % of the Ni catalytic system in a basic aqueous solution for 1 h, giving the corresponding 2-aryl allyl phosphonates
一种操作简单且绿色的方案,使用 NiSO 4 ·6H 2 O/阳离子 2,2'-联吡啶配体系统作为水溶性催化剂,用于芳基硼酸与 (2-卤代烯丙基) 膦酸酯和 (2-卤代烯丙基) 砜的偶联开发了在空气中的水中。在 5 mol% Ni 催化体系存在下,在碱性水溶液中,用芳基硼酸(2 mmol)和(2-卤代烯丙基)膦酸酯或砜(1 mmol)在 120 °C 下反应 1 小时,得到相应的2-芳基烯丙基膦酸酯或砜的产率良好至优异。该反应的特点是在水中使用丰富的过渡金属作为催化剂,并表现出高官能团耐受性,使其成为一种环境友好的过程。
