Abstract:
The invention relates to general syntheses of (6H)-dibenz[c,e] [1,2]-oxaphosphorins which are substituted with nitrogen compounds on the phosphorus atom and comprising commercially available 6H-dibenz[c,e] [1,2]-oxaphosphorin-6-oxides. These nitrogen-containing (6H)-dibenz[c,e] [1,2]-oxaphosphorins can be used as reactive starting substances for further syntheses or as flameproofing agents or as stabilisers.
