A regioselective O/C phosphorylation of α-chloroketones with trialkyl phosphites was performed for the first time, which employed solvent-free Perkow reaction and NaI-assisted Arbuzov reaction under mild conditions respectively. Versatile enol phosp

Organophosphorus compounds occupy a significant position among the plethora of organic compounds, but a limited number of paramagnetic phosphorus compounds have been reported, including paramagnetic phosphonates. This paper describes the syntheses an

A novel methodology for the synthesis of functionalised indoles based on the cross-coupling reactions of 3-bromo-2-indolyl phosphates is described. The preparation involves the conversion of easily available 2-oxindoles to 3,3-dibromo-2-oxindoles fol

An inorganic base-promoted domino reaction with organophosphites and acyl cyclopropane derivatives is developed and proved to provide an efficient access to functionalized enol phosphates. Unlike the well-known Perkow reaction, which employs trialkyl

A one-pot, four-component synthesis of imido phosphates has been achieved using a Nef–Perkow sequence followed by addition of carboxylic acid derivatives. The final imido moiety is formed via a Mumm rearrangement of an intermediate imidate.

Two competitive mechanistic pathways for the reaction between trimethyl phosphite and chloroacetone are analyzed by high-level calculations. FMO analysis and HSAB-derived descriptors point to a preferential initial interaction of the nucleophile with

Imidoyl chlorides, generated from isocyanides and acyl chlorides, react with trialkyl phosphites, in a Perkow-type reaction, to afford 3-(alkylimino)-2-[(dialkyloxyphosphoryl)oxy]acrylates, which undergo a smooth reaction with tosylmethyl isocyanide
