摘要：This invention relates to novel substituted 2-hydroxy-2- phosphinyl ethanals ofthe general Formula I. ##STR1## to 1,2-dihydroxy-1, 2- bisphosphinylethanes of thegeneral Formula II ##STR2## to methods of making the same, to compositions containingcompounds of the general Formula I, and/or of the general Formula II, to the use of suchcompositions to impart flame-resistance to cellulose and cellulose containing materials,to flame-resistant compositions containing compounds of the general Formula II and tothe use of the compounds of the general Formula II as metal complexing agents.

In the compounds of the Formulas I and II R.sub.1 and R.sub.2 may be the same ordifferent radicals including alkoxy, aryloxy, arylalkoxy, cycloalkoxy, alkyl, alkenyl, aryl,aralkyl, cycloalkyl as well as such radicals containing substituents such as halogen, amino,hydroxy, alkoxy, mercapto, carboxy, carbalkoxy and the like in addition R.sub.1 and/or R.sub.2 may be hydroxy.
