Diarylphosphoryl azide

WebChemoselective annulations of phosphoryl carbenes generated from diazo (aryl)methyl (diaryl)phosphine oxides with pyridinium 1,4-zwitterionic thiolates were performed under microwave irradiation, affording 1-diarylphosphoryl-1 H -benzo [ c ]thiopyran derivatives via [3+3] annulation and indolizine derivatives via ( [1+5]-1) annulation with P-Cope … Websodium azide was found to give benzoyl azide ( 4), as shown in Scheme 1. Although this reaction proceeded in two steps from benzoic acid (1), I thought that the acyl phosphate 6 would be temporally formed if the phosphorazidate 5 were used in place of the phosphorochloridate 2, and the acyl phosphate 6 would react in situ with the azide ion …
