ABSTRACT:
Novel .alpha.-aminoacetamides are powerful stabilizers for organic materials subject to oxygen and heat degradation, and particularly for synthetic natural rubber and synthetic ester lubricants. A wide range of substituents on the amine and amide N atoms, and also 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 dichlorocarbene 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 dichlorocarbene ion generating agent is a haloform. The alkoxide ion generating agent may be a ketone, an aldehyde, or a cyanohydrin which reacts with the haloform. An .alpha.-trihalomethyl alcohol also reacts with the amine nucleophilic agent, without the benefit of a dichlorocarbene ion generating agent. When the alkoxide ion generating agent is an .alpha.-trihalomethyl alcohol, an .alpha.-hydrogen may optionally be substituted.
