Alteration of the course of the Michaelis–Arbuzov reaction in imidazolium ionic liquids

Room-temperature imidazolium ionic liquids [Rmim][X] (X=Br, BF₄, NTf₂) as a reaction medium change the reaction course of phosphorus(III) acid esters with primary alkyl halides, aryl bromides, and propargyl bromide to afford hydrophosphoryl compounds, products of oxidation of the starting phosphorus substrates, and 2,3-bis(phosphoryl)prop-1-enes, respectively.
