## Abstract Base‐catalysed addition of phenylacetonitrile to 1‐methyl‐3‐cyano‐1, 6‐dihydropyridine (II) is shown to give α‐[1‐methyl‐3‐cyano‐1.4.5.6‐tetrahydro‐pyridyl‐(4)]‐phenylacetonitrile (VI). The structure of VI has been proved by its reduction to the saturated dicyano compound VIII, which ha

Abstract
The reaction of 1‐methyl‐3‐cyano‐1, 6‐dihydropyridine with acrylonitrile is shown to give the two possible stereoisomers of 2‐methyl‐6, 7‐dicyano‐2‐aza‐bicyclo[2, 2, 2]‐octene‐(5) (I and II). A polar non‐concerted two‐step mechanism for this cyclo‐addition is proposed.
