Anwendungen
VerwendenBenzhydryl bromide is a halogenated building block. Benzhydryl group was preferred to the commoner benzyl to protect 2-nitrophenol in the Bartoli (vinyl Grignard) synthesis of 7-hydroxyindole. Protection was by reaction with the phenol in the presence of potassium carbonate in acetone; deprotection of the indole was by hydrogenolysis.
