Palladium-Catalyzed Formylation of Enol Triflates and lodoalkenes

Palladium-Catalyzed Formylation of Enol Triflates and lodoalkenes 

Formate salts [69] or formic add under conditions converting them electrodiemically into formate [70,71], sUyl, and tin hydrides have been also explored to perform formylations of organic halides/triflates under lower pressure of carbon monoxide. Acetic formic anhydride has been used as a source of carbon monoxide for the conversion of aryl iodides in conjunction with RsSiH [72]. The palladium-catalyzed formylation of a wide variety of vinyl iodides and triflates with tin hydride and carbon 

Trapping of 0(,P-Unsaturated Acylpalladium with Active C-H Compounds 

Acylpalladium complexes can be generated through an intramolecular carbopaUada-tion/carbonylation sequence of vinyl iodides/triflates bearing a proximate alkene or
