An efficient phosphorylation of C(sp3)-H bonds of arenes with diaryl phosphinic acids via Bu4NI-catalyzed dehydrogenative coupling has been developed. This transformation proceeds efficiently under transition-metal-free reaction conditions and represents a straightforward method to prepare valuable organophosphorus compounds from readily available arenes and diaryl phosphinic acids.

A Tf2O/DMSO-based system for the dehydrogenative coupling of a wide range of alcohols, phenols, thiols, and thiophenols with diverse phosphorus reagents has been developed. This metal- and strong-oxidant-free strategy provides a facile approach to a great variety of organophosphinates and thiophosphates. The simple reaction system, good functional-group tolerance, and broad substrate scope enable the application of this method to the modification of natural products and the direct synthesis of bioactive molecules and flame retardants.

Paragraph 0030-0040, (2020/07/29)
The invention provides a high-efficiency and high-selectivity synthetic method for organic phosphate derivatives containing different substituted functional groups. The method uses tetrabutylammoniumiodide as a catalyst and uses a P(O)-OH-containing compound and a methyl-containing aromatic hydrocarbon compound as reaction substrates, and an organic solvent and an oxidant are added in the reaction system. The method has the advantages that the catalyst is cheap and easy to obtain, the substrate applicability is high, the reaction conditions are mild, safe and reliable, the selectivity of an obtained target product is close to 100%, and the yield is up to 90% or more. The method solves shortages in traditional organic phosphate ester compound synthetic methods that reaction selectivity ispoor, reaction steps are complicated, the yield is low, environmentally-harmful agents are used and the like, and has better industrial application prospects. The invention also provides the corresponding organic phosphate derivatives containing the different substituted functional groups.
