Abstract An efficient, environmentally benign and one‐pot approach for the synthesis of 2‐arylimino‐2 H ‐chromenes from 2‐hydroxybenzyl alcohols β‐ketothioamides at room temperature under visible light has been developed. The reported reaction conditions were favorable a wide range afforded good to excellent yields respective products. low cost air stable Knölker iron catalyst employed dehydrogenation photolysis that would usually require higher temperature.

The iron(III) salen complex (R,R)-N,N'-bis(salicylidene)-1,2-cyclohexanediamineiron(III) chloride has been developed as a catalyst for the acceptorless dehydrogenation of alcohols. catalyzes direct synthesis imines in good yields from different primary alcohols and amines with liberation hydrogen gas. mechanism investigated experimentally labelled substrates theoretically density functional theory calculations. In contrast to corresponding manganese(III) salen-catalyzed dehydrogenation, it not possible identify homogeneous catalytic pathway iron complex. Instead, poisoning experiments trimethylphosphine mercury indicated that catalytically active species are heterogeneous small particles.
