Organophotocatalytic Synthesis of Phosphoramidates

We describe the use of visible light in conjunction with an organic dye for the synthesis of phosphoramidates. Cross dehydrogenative coupling reactions between phosphites and amines are reported using organic dyes and light as catalysts for the first time. It is not only a novel application of organic dyes but also fulfils the requirement of sustainability and green chemistry avoiding the use of chromatographic purification techniques. The product was simply isolated from the reaction mixture via an acid-base work-up procedure, rendering the pure product in good yields.

Iodine catalyzed solvent-free cross-dehydrogenative coupling of arylamines and H-phosphonates for the synthesis of N-arylphosphoramidates under atmospheric conditions

Aerobic oxidative coupling of various arylamines and H-phosphonates to the corresponding N-arylphosphoramidates has been achieved under solvent-free conditions using molecular iodine. This protocol works at room temperature furnishing the corresponding P-

Practical and reliable synthesis of dialkyl N-arylphosphoramidates with nitroarenes as substrates

A new single-step transformation of readily available nitroarenes with trialkyl phosphites, which can be performed both under thermal and microwave conditions, delivers dialkyl N-arylphosphoramidates in good yields and short reaction times.

Diethyl chlorophosphite: A versatile reagent

Diethyl chlorophosphite (DECP) was previously described as a reducing agent for nitro compounds to the corresponding amines (Fischer, B.; Sheihet, L. J. Org. Chem. 1998, 63, 393). Here, the utility of this reagent was extended to chemical conversions of other oxygenated functional groups. In this paper we report on the scope of the reaction of DECP with N-oxides, epoxides, sulfones, sulfoxides, hydroxylamines, ketoximes, and aldoximes. The chemoselectivity of DECP is described, and conditions for a stepwise multiple conversion of functional groups on the same molecule with this reagent are provided.
