Herein, we describe an efficient, practical photocatalytic deoxygenation/defluorination protocol for the synthesis of γ,γ-difluoroallylic ketones from com. available aromatic carboxylic acids, triphenylphosphine, and α-trifluoromethyl alkenes. The protocol has good functional group tolerance and a broad substrate scope. Using this method, we accomplished the late-stage functionalization of several bioactive mols. The experimental part of the paper was very detailed, including the reaction process of Pyridin-3-ylboronic acid(cas: 1692-25-7Electric Literature of C5H6BNO2)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Electric Literature of C5H6BNO2
