Rhodium(I) catalysis demonstrates enantioselective and diastereoselective arylation, highlighting new fluoroalkenes.
Comprehensive Summary We herein describe an enantio‐ and diastereoselective rhodium(I)‐catalyzed defluorinative arylation of pentafluoroethyl alkenes with arylboronic acids. A new class of previously inaccessible functionalized fluoroalkenes featuring a sp 2 ‐carbon connected to F and CF 3 can be synthesized. Using both 1,1‐ and 1,2‐disubstituted alkene substrates, tetra‐ and trisubstituted fluoroalkene products are obtained in excellent Z / E selectivities with well‐defined alkene geometry. These fluoroalkenes are potential synthons for accessing chiral compounds containing a stereogenic centre with F and CF 3 group.
