The transfer‐hydrogenative cyclization of 1,6‐diynes with Hantzsch 1,4‐dihydropyridine as a H 2 surrogate was performed in the presence of a cationic ruthenium catalyst of the type [Cp′Ru(MeCN) 3 PF 6 ]. Exocyclic 1,3‐dienes or their 1,4‐hydrogenation products, cycloalkenes, were selectively obtained, depending on the substrate structure and the reaction conditions.
