Abstract: Abstract A palladium-catalyzed and norbornene-mediated Catellani reaction was developed through ortho-acylation and ipso-alkynylation for the aryl iodides. Acyl chlorides were used as acylation reagents and phenylpropiolic acids were used as termination reagents respectively in this… read more here.
