Benzotriazole‐mediated indirect electrophilic substitution in the position para to the oxygen atom of benzo[ b ]pyrylium salts has been used for the synthesis of long‐chain and bifunctional benzo[ b ]pyrylium species. The methodology has potential for application in high technology and the pharmaceutical industries, for the molecular engineering of new functionalized derivatives.
