2-Benzopyrylium perchlorates 3 react with potassium cyanide to the isochromen-1-carbonitriles 4. Grignard compounds substitute the nitrile function in 4 to give the 1,1-disubstituted 3-phenyl-isochromens 5.
2-BENZOPYRYLIUM SALTS. 43. CONVERSION OF DIMERS OF 2-BENZOPYRYLIUM SALTS TO BENZOFURAN DERIVATIVES
Verin, S. V.,Kuznetsov, E. V.
, p. 135 - 138 (2007/10/02)
In the acid-catalyzed interaction of dimers of 2-benzopyrylium salts with peracetic acid and hydrogen peroxide, the oxidation products that are formed are readily converted to benzofuran derivatives.
2-BENZOPYRILIUM SALTS. 38. A NOVEL VARIANT OF THE CANNIZZARO REACTION
Verin, S. V.,Kuznetsov, E. V.
, p. 866 - 868 (2007/10/02)
1,5-Aldehydoketones (the ring-opened forms of 2-benzopyrylium salts) under the conditions of the Cannizzaro reaction, when intramolecular aldol condensation is not possible, undergo intramolecular disproportionation.
