ABSTRACT:
New hydroxyphenylated hydantoins are useful as stabilizers for synthetic organic polymeric materials. The new hydroxyphenylated hydantoins may be additionally substituted in the 1,3 and/or 5 positions of the hydantoin ring.
The hydroxyphenylated and 5-substituted hydroxyphenylated hydantoins are generally prepared by reacting hydroxyphenylated ketones or aldehydes with alkali cyanide and ammonium carbonate. Hydroxyphenylated hydantoins substituted in the 1 and/or 3 positions are generally prepared by reacting the 1 and/or 3-unsubstituted hydroxyphenylated hydantoins with the corresponding halogen or dialkylaminomethyl derivatives.
