WebThus nitrobenzene (a deactivated ring) fails to react in the Friedel-Crafts reaction. However the reaction is successful with halogen substituents are present, as in chlorobenzene. The Friedel-Crafts alkylation of methoxy benzene would be expected to produce a mixture of the ortho and para substituted products, but no meta -substituted product. WebThe nitration of methylbenzene (toluene) Methylbenzene reacts rather faster than benzene - in nitration, the reaction is about 25 times faster. That means that you would use a lower temperature to prevent more than one nitro group being substituted - in this case, 30°C rather than 50°C. Apart from that, the reaction is just the same - using ...
