Methyl 9,12-dioxo-octadeca-trans-10-enoate undergoes Diels-Alder reaction with isoprene, with 2,3-dimethylbutadiene, and with methyl octadeca-trans-9,trans-11-dienoate to give substituted cyclohexenes. Clemmensen reduction of the cycloaddition product from the last-mentioned compound does not proceed...
What is Friedel Craft reaction with example? An alkyl group can be added by an electrophillic aromatic substitution reaction called the Friedel-Crafts alkylation reaction to a benzene molecule. The addition of a methyl group to a benzene ring is one example. To form a nonaromatic carrbocation...

The Friedel-Crafts reaction is a typical electrophilic substitution reaction in the aromatic nucleus; the role of the catalyst amounts to the generation of an attacking particle—an alkyl or acyl cation. Examples are given below of the interaction of benzene with the ethyl chloride and the acid ...
The Friedel-Crafts alkylation synthesizes alkylated products, such as alkylbenzenes, via the reaction of alkyl halides or alkenes with aromatic hydrocarbons. The reaction removes a hydrogen atom on the aromatic ring and replaces it with an electrophile. Thus, it occurs via electrophilic aromatic s...
EARLIER work has shown that pure isobutene gas and pure di-isobutene vapour do not undergo reaction when mixed with gaseous boron trifluoride. In the presence of a trace of some third component, or cp-catalyst as we shall call it, these ... AG Evans,GW Meadows,M Polanyi - 《Nature》 被...
Crosslinked polystyrene particles were prepared by Friedel–Crafts suspension crosslinking of polystyrene using 2,4-dichloromethyl-2,5-dimethyl benzene as crosslinking agent. The polymer was dissolved in nitrobenzene and reaction occurred in a 70 wt % aqueous solution of ZnCl2 with poly(vinyl alcohol...
