I found the field of Chemistry very interesting. Saw the article Palladium-Catalyzed Regioselective C-H Iodination of Unactivated Alkenes published in 2019. Category: Pyrazines, Reprint Addresses Carreira, EM (corresponding author), Swiss Fed Inst Technol, HCI, Vladimir Prelog Weg 3, CH-8093 Zurich, Switzerland.. The CAS is 98-97-5. Through research, I have a further understanding and discovery of Pyrazine-2-carboxylic acid
A palladium-catalyzed C-H iodination of unactivated alkenes is reported. A picolinamide directing group enables the regioselective functionalization of a wide array of olefins to furnish iodination products as single stereoisomers. Mechanistic investigations suggest the reversible formation of a six-membered alkenyl palladacycle intermediate through a turnover-limiting C-H activation.
