This invention relates to novel flame retarding agents and processes in which they are used in the production of polyurethanes. These compounds are represented by the general formula: ##STR1## wherein: A and L, which are identical or different, represent optionally branched C.sub.1 -C.sub.17 -alkyl groups or -OR groups wherein R represents an optionally branched C.sub.1 -C.sub.8 -alkyl group, and X represents hydrogen, halogen, an optionally branched C.sub.1 -C.sub.8 alkyl group, a C.sub.6 -C.sub.12 aryl or aralkyl group, NH.sub.2, CF.sub.3, CN, COOR', SO.sub.3 R', ##STR2## wherein: R' represents hydrogen or an optionally branched alkyl or cycloalkyl group having 1-10 C atoms and R" represents an optionally branched alkyl or cycloalkyl group having 1-10 C atoms.
