A powerful method for versatile phosphine synthesis: The P–C coupling of hydroxymethylphosphine sulfide derivatives with various aryl bromides and triflates to yield triarylphosphine sulfides has been developed. The new method was successfully applied to the sequential triple coupling of an orthogonally protected precursor to give an unsymmetrically substituted triarylphosphine sulfide.
通用膦合成的有效方法:已开发了羟甲基膦硫化物衍生物与各种芳基溴化物和三氟甲磺酸酯进行P–C偶联以产生三芳基膦硫化物的方法。该新方法已成功应用于正交保护的前体的顺序三重偶联,从而得到不对称取代的三芳基膦硫化物。
