The synthesis of nitrile ligands linked to tricarbonyl (η 6 -arene)chromium complexes by conjugated spacers is performed by reacting aromatic bromo nitrile derivatives with tricarbonylchromium-complexed phenylacetylene using Sonogashira coupling reaction.
In the 2H-chromene series, complexation of the aromatic ring with chromium tricarbonyl, under thermal conditions, is totally regioselective even when aromatic substituents are introduced on the pyran ring. The complexation stabilizes the open form of these photochromic compounds and reduces the ther
