phenyl-H-phosphinic acid (6) are converted to the corresponding phosphinic esters (2, 4, and 7, respectively) by reaction with simple alcohols on microwave irradiation. Under traditional heating conditions, the esterification does not take place, as in the cases of 1 and 3, or is highly incomplete, as in the case of 6. Steric hindrance in diphenylphosphinic acid prevents efficient microwave-assisted esterification
摘要 1-羟基-3-环磷烯氧化物(1 和 3)和苯基-H-次膦酸(6)通过在微波辐射下与简单醇反应转化为相应的次膦酸酯(分别为 2、4 和 7)。在传统加热条件下,酯化不会发生,如在 1 和 3 的情况下,或者是高度不完全,如在 6 的情况下。二苯基次膦酸中的空间位阻阻止了有效的微波辅助酯化。
