Abstract

Provided is a complex of hydrogen peroxide and at least one compound represented by Formula I:wherein X is:—C(R3)3, —C≡C(R3), —O(R3), —N(R3)2, or —S(R3); and R1, R2, and R3 are each independently selected from H, alkyl, alkenyl, alkynyl, aralkyl, aryl, heteroaryl heteroarylalkyl, heterocyclyl, and cycloalkyl, or R2 and an R3 are optionally taken together to form an alicyclic ring. Also provided are anaerobic cure systems and curable compositions employing the complexes described herein.
