A new method for the preparation of nitrogen-containing cyclic compounds from p-nitrobenzenesulfonamide and alkyl bis (diphenylphosphinite) s by oxidation- …
It was recently reported from our laboratory that an oxida- tion-reduction condensation using a combination of alkyl di- phenylphosphinites (Ph2POR), prepared from alcohols and chlorodiphenylphosphine (Ph2PCl), and quinones such as 2,6-di- methyl-1,4-benzoquinone and 2,6-di-tert-butyl-1,4-benzoqui - none is successfully applied to the syntheses of esters,1 ethers,1b,2 alkyl nitriles,3 alkyl aryl sulfides,4 alkyl amides,5 and isocya- nides.6 More recently, a new synthetic method of ...
