Synthesis of water-soluble phosphine oxides by Pd/C-catalyzed P-C coupling in water

10.1021/ol300582y

This research presents a green, simple, and fast protocol for synthesizing water-soluble tertiary phosphine oxides through Pd/C-catalyzed P-C coupling in water. The purpose is to develop an environmentally friendly and sustainable method for carbon-phosphorus coupling that produces water-soluble phosphine derivatives, which have advantages in industrial processes based on homogeneous catalysts. Key chemicals used include diphenylphosphine oxide as the P-source, halogenated benzoic acids as coupling partners, and Pd/C as the catalyst. The reaction is performed in water, with microwave irradiation and K2CO3 as the base. The method allows for the synthesis of several new phosphine oxides with high yields and purity, without the need for organic solvents in reactions and workup. The protocol is also recyclable and scalable, making it a promising candidate for both laboratory and large-scale synthesis.
