ABSTRACT:
Unsaturated amines, primary and secondary saturated amines, N,N,N',N'-tetramethylethylenediamine, N,N,N',N'-tetramethyl-1,3-propanediamine, and ammonia cocatalysis with alkali metals for alkenylation of alkylaromatics having benzylic hydrogen with conjugated diolefins of 4-15 carbon atoms. Improved trans:cis product ratio and improved yield are produced by these nitrogen containing cocatalysts.
