A new selective method for the nitration of m-cresol has been established. 3-Methyl-6-nitrophenol was most efficiently prepared by nitration of 3-methyl-4-sulfophenyl carbonate or phosphate and subsequent hydrolysis and desulfonation. Steric effects on the attacks of sulfonium or nitronium ion to the phosphate are discussed.
Anhand der Isomerenverteilung der Nitro‐3‐methyl‐ ′phenole (II), die durch Sulfonierung und anschließende Nitrierung verschiedener Ausgangsmaterialien wie (I) und (III) unter verschiedenen Bedingungen erhalten werden, wird eine selektive Methode zur Darstellung der Titelverbindung festgelegt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations –citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
