2-hydroxy-2-phosphinyl ethanals and 1,2-dihydroxy-1,2- bisphosphinyl ethanes

摘要

This invention relates to novel substituted 2-hydroxy-2- phosphinyl ethanals of the general Formula I. ##STR1## to 1,2-dihydroxy-1, 2- bisphosphinylethanes of the general Formula II ##STR2## to methods of making the same, to compositions containing compounds of the general Formula I, and/or of the general Formula II, to the use of such compositions to impart flame-resistance to cellulose and cellulose containing materials, to flame-resistant compositions containing compounds of the general Formula II and to the use of the compounds of the general Formula II as metal complexing agents.PPIn the compounds of the Formulas I and II R.sub.1 and R.sub.2 may be the same or different 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.
