Cure accelerators for anaerobic curable compositions, such as adhesives and sealants, are provided, and which are defined with reference to the compounds shown in structure (I); where A is CH2 or benzyl, R is C1-10 alkyl, R' is H or C1-10 alkyl, or R and R' taken together may form a four to seven membered ring fused to the benzene ring, R" is optional, but when R" is present, R" is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene (meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl, and EWG is as shown, an electron withdrawing group, such as nitro, nitrile, carboxylate or trihaloalkyl. |
