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

Abstract An efficient, catalyst-free and solvent-free protocol has been developed for the synthesis of phosphoramidates. This method can be used to synthesize phosphoramidates from diverse starting materials including aryl/benzyl and alkyl azides at room temperature. The synthesis is simple, selective and high yielding with notably a very short reaction time. The process involves mild reaction 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-N coupling products in moderate to high yields. (C) 2014 Elsevier Ltd. All rights reserved.
