Alkylbenzenes underwent regioselective fluorination with N-fluorobenzenesulfonimide in the presence of CuOAc and bathophenanthroline mediated by methylboronic acid and lithium carbonate in chlorobenzene to yield secondary and tertiary benzylic fluorides. The benzylic fluorides generated in these reactions were reactive electrophiles in the presence of the hydrogen-bond donor hexafluoroisopropanol or the Lewis acid BF3¡¤Et2O, yielding benzylic ethers, alcs., protected amines, and diarylalkanes directly from the alkylarenes.
Organic Letters published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C22H23BO4, Synthetic Route of 457-68-1.
