The structure of 294 was confirmed by single-crystal X-ray crystallographic analysis (Eq. 84).123,124 (84) Iodine-induced cyclization reaction of 1,2-di(1H-pyrrol-1-yl)benzene 295 in chlorobenzene under dark conditions furnished dipyrrolo[1,2-a:2′,1′-c]quinoxaline 296 in 85% yield. ...
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 su...
What is the major product in the Friedle-Craft Alkylation reaction using 1,4-dimethoxybenzene and 3-methyl-2-butanol, also included in the reaction are H_2SO_4 and CH_3COOH. What is the mechanism behind this reaction? What is the structure and IUPAC...
Friedel-craft acylation illustrates the substitution reaction of benzene which "substitutes the acyl group." The "Lewis acid" has significance in carrying out the Friedel craft reaction. The loss of chlorine occurs through "complex formation with Lewis ...
