A concise synthesis of 1‐naphthols via cyclization of o‐iodoacetophenones and methyl ketones has been realized under very mild conditions. The cyclization process is initiated by a rare copper‐catalyzed arylation of simple methyl ketones with ortho‐iodoacetophenones.

An efficient protocol for the straightforward, single‐step synthesis of 3‐aryl‐1‐indanones from 2′‐iodochalcone via reductive Heckreaction using phosphine free, stable and reusable binaphthyl stabilized palladium nanoparticle (Pd‐BNP) as a catalyst has been described. An immense array of substrate scope with electron‐rich and deficient 2′‐iodochalcones have been synthesized. Further derivatization
A Pd-catalyzed cascade Ullmann coupling–aldol–dehydration reaction of ortho-acylphenyl iodides affords colchino analogues with wide functional group tolerance.
