Abstract
A compound of formula ##STR1## where R.sup.1 and R.sup.2 are independently a C.sub.1 -C.sub.10 aliphatic radical, or R.sup.1 is a C.sub.1 -C.sub.10 aliphatic radical and R.sup.2 is a C.sub.6 -C.sub.10 aromatic radical, and R.sup.3 is a C.sub.1 -C.sub.8 aliphatic radical, a C.sub.3 -C.sub.8 cycloaliphatic radical, a C.sub.6 -C.sub.15 aromatic radical or a C.sub.7 -C.sub.13 araliphatic radical, provided that R.sup.3 is not methyl when R.sup.1 and R.sup.2 are each methyl, that R.sup.3 is not ethyl when R.sup.1 and R.sup.2 are each methyl and that R.sup.2 is not p-aminophenyl when R.sup.1 is methyl and R.sup.3 is ethyl with an organic compound having at least one group reactive with a P--H bond.
