ABSTRACT:
Novel .alpha.-aminoacetamides are powerful stabilizers for organic materials subject to oxygen and heat degradation, and particularly for synthetic natural rubber, synthetic ester lubricants and synthetic resinous materials. A wide range of substituents on the amine and amide N atoms, at least one of which substituents is an alkylene imine (cyclic), and an even wider range of substituents on the saturated carbon atom, yields an array of stabilizers having a wide range of compatibility in compositions comprising various synthetic resinous compounds to be stabilized.
Novel syntheses are provided utilizing at least one amine nucleophilic agent, a trichloromethide ion generating agent, and an alkoxide ion generating agent, which together in the presence of aqueous alkali and an onium salt, yield novel .alpha.-aminoacetamides in which a wide choice of substituents may be introduced. The nucleophilic agent may be a primary or secondary amine, or one of each. The trichloromethide ion generating agent is a haloform. The alkoxide ion generating agent may be a ketone, or an aldehyde which reacts with the haloform.
