Reactions of 7-methoxyimino-4-methylchromene-2,8-dione with phosphines. Preparation of N-substituted 7-amino-8-hydroxy-4-methyl-2H-[1]-benzopyran-2-ones

7-Methoxyimino-4-methylchromene-2,8-dione 2 reacts with triarylphosphines 1(a-d) to give the unexpected 7-arylomino-8-hydroxy-4-methyl-2H-[1]-benzopyran-2-ones 7(a-d) and methyl diarylphosphinates 8(a-d) in high yields. The reaction of 2 with trialkylphosphines 1(e,f) as well as with diphenylphosphine 15 leads to the formation of the N-dialkylphosphinoyl derivatives 11, 12, 14 and the N-diphenylphosphinoyl derivative 19, along with compounds 7(e,f). The methylation of compounds 7a, 7f, 11 and 19 is also studied and reaction mechanisms to explain the formation of the products obtained are suggested.

Electrochemical Dehydrogenative Phosphorylation of Alcohols for the Synthesis of Organophosphinates

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
