Ar. Katritzky et al., CONVERSION OF ALDEHYDES TO ALPHA-ACETOXYMETHYL KETONES - ONE-CARBON HOMOLOGATION WITH (BENZOTRIAZOL-1-YL)PHENOXYMETHANE, Tetrahedron letters, 36(6), 1995, pp. 841-844
Reaction of aldehydes with (benzotriazol-1-yl)phenoxymethyl anion affo
rded the corresponding addition products which, upon treatment with p-
toluenesulfonic acid in acetic acid, yielded the corresponding alpha-a
cetoxymethyl ketones.
