The compounds are trialkylsubstituted hydroxybenzylphosphonates and phosphinates having the formula SPC1 Wherein R, R1 and R2 are independently lower alkyl or cycloalkyl groups, R3 is alkyl, alkyl substituted with one halogen atom, phenyl, phenyl substituted with alkyl groups, alkoxy, alkoxy substituted with one halogen group, phenoxy, phenoxy substituted with alkyl groups, alkylthioethoxy, alkylpolyoxyalkylenoxy, R4 is alkyl, alkylsubstituted with one halogen atom, cycloalkyl, phenyl, phenyl substituted with alkyl groups alkylthioethyl, thiobis-alkylene, alkyleneoxyalkylene, polyoxyalkylene, alkylpolyoxyalkylene, alkylene, polyvalent cyclic or acyclic hydrocarbon radical, R 5 and R 6 are independently hydrogen, alkyl of 1 to 12 carbon atoms, R6 may also be the group Ic SPC2 Or together R5 and R6 represent the group Id SPC3 R7 is hydrogen, alkyl or phenyl, A is lower alkylene and n is 1 to 4. These compounds are usually prepared by reacting the trialkylsubstituted hydroxybenzyl or hydroxyphenylalkyl halide with the appropriate trialkyl or triaryl phosphite or appropriate substituted phosphonite. The compounds are useful as stabilizers of organic materials subject to oxidative, thermal and photochemical degradation.
