A phosphoryl radical-initiated Atherton-Todd-type reaction using air as the radical initiator and CHCl3 as the halogenating reagent for the phosphorylation of alcohols, phenols, and amines has been developed. This novel transformation provides a highly efficient route to important phosphinates, phosphinic amides, and phosphoramidates in up to 99% yield with a broad substrate scope under very mild conditions

An eco-friendly and efficient method for the synthesis of organophosphinates via an electrochemical cross-dehydrogenative-coupling reaction between alcohols and secondary phosphine oxides has been developed. This electrochemical reaction was conducted at room temperature without the addition of any oxidant, metal catalyst, or additive, which provides a new strategy for the synthesis of organophosphinates

in its activity with acetylsalicylic acid. In contrast to the latter acid, this oxide produces no ulcerogenic effect even at a dose of 1/3 LD50. Therefore, it was of interest to continue the search for new antiinflammatory and analgesic agents in the series of phosphoryl-containing compounds. The purpose of this work was to study the antiinflammatory and analgesic properties and the acute toxicity of
