Abstract
The reaction of (4-R-benzoyl)(2-bromopyridinitim) methylides with ethoxyrnethylene-rnalononitrile is stereoselective and affords Z-1-[1-(4-R-benzoyl)-2-ethoxyvinyl]-2-dicyationietliylene-1,2-dihydropyridines. The structure of 1-[1-(4-chlorobenzoyl)-2 ethoxyvinyll-2-dicyanomethylene-1,2-dihydropyridine has been established by X-ray structural study.
