3,3-Bis(diethylphosphono)-1(3H)-isobenzofuranone and Its Properties

The reaction of o-phthaloyl chloride with sodium diethylphosphite led to the formation of new 3,3-bis(diethylphosphono)-1-(3H)-isobenzofurane 1. The reaction of bis-phosphonate with alkylamine occurs with replacement of an ester oxygen by an imine group to afford the crystalline isoindolyl-bis-phosp...

Summary:The reaction of o-phthaloyl chloride with sodium diethylphosphite led to the formation of new 3,3-bis(diethylphosphono)-1-(3H)-isobenzofurane 1. The reaction of bis-phosphonate with alkylamine occurs with replacement of an ester oxygen by an imine group to afford the crystalline isoindolyl-bis-phosphonate-a representative of this new type of organophosphorus heterocycles.
