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 0015, (2018/12/14)
The invention belongs to the technical field of organic synthesis, discloses a method for synthesis of organophosphorus compound by photo-induced iodine catalyzed Atherton-Todd reaction. The method comprises the following steps: a compound shown as formula II and a nucleophilic reagent are subjected to reaction for 24 hours in a dichloromethane solvent, an oxygen atmosphere, under irradiation condition of room temperature and the action of a halogenated reagent I2, then the organophosphorus compound shown as the formula II is obtained through washing, drying, separating and purifying. According to the the method provided by the invention, compared with traditional Atherton-Todd reaction, no catalysis of metal is needed,no addition of alkali is needed, reaction environment such as metal, high temperature and strong base is replaced, a series of organophosphorus compounds can be synthesized by catalyzing a variety of substrates under the irradiation condition of room temperature, and hasthe advantages of good universality, short reaction time and higher yield.

A novel base-promoted O-deprotonation/alkylation reaction of P(O)-OH compounds with alkyl halides has been developed. The protocol is practical, representing a simple way to produce a broad spectrum of functionalized phosphinates, phosphonates, and phosphates from basic starting materials with good to excellent yields. A plausible mechanism was proposed for this reaction.
