Reactions of β-dimethylaminoacrolein aminal and 3-dimethylamino-1,1,3-trimethoxypropane with alkylidenemalononitriles

Add time:07/11/2019    Source:sciencedirect.com

The reaction of alkylidenemalononitriles with β-dimethylaminoacrolein aminal unexpectedly results in (3-dimethylaminopropen-1-ylidene)malononitrile, whereas the reaction of 1-dimethylamino-1,3,3-trimethoxypropane gives unknown ω,ω-bis(3-dimethylaminopropen-2-ylidene)alkylidenemalononitriles.
