ABSTRACT:
The following new compounds were prepared from cyanoguanidine or guanylurea as potential flame retardants for cellulosic textiles -2-cyano-1-[bis-(dimethylamino)phosphinyl]guanidine, 2-cyano-1-(diethoxyphosphinyl)guanidine, and 2-carbamoyl-1-(diethoxyphosphinyl) guanidine. The successful phosphorylation of guanylurea required use of a dry, aprotic solvent.
