Platinum(II) photo-catalysis for highly selective difluoroalkylation reactions


1.  The platinum(II) photo-catalyzed difluoroalkylation of cinnamic acids and alkynes for selective construction of E-,Z-difluoroalkyl alkenes and difluoroalkyl alkenyl iodides, respectively, were achieved under mild conditions. The high efficiency, good substrate scope and high selectivity altogether highlight the prospect of Pt(II) photocatalysts in visible-light-driven organic transformation reactions.(Chem.
