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...
Additionally, a scale-up reaction with 1,2-dimethoxybenzene as a substrate gave a 65% yield of the corresponding product 42. Benzenes bearing trisubstitutions such as 1,3,5-trimethoxybenzene 44 and 1-bromo-3,5-dimethoxybenzene 45 were also found to be suitable substrates and underwent these ...

Products of the reaction of 3-halo- and 3-ethoxypropionic acids with 1,3-dimethoxybenzene (4) in polyphosphoric acid have been shown to be 2',4'-dimethoxy-3-(2,4-dimethoxyphenyl)-propiophenone (6) and 1,5-bis[3-(2,4-dimethoxyphenyl)-3-keto-propyl]-2,4-dimethoxybenzene (15) and ...
Derivatives of 1,3-dimethoxybenzene have previously been found to selectively protonate at C2 upon excitation in HFIP, and indeed the principal products with 4 are 1,3-dimethoxybenzene ( 6 ) and Ph 2 CHOCH(CF 3 ) 2 ( 7 ), the species expected if the cyclohexadienyl cation formed in ...
Similar reaction with 1,2,3-trimethoxybenzene (1b) gave only reasonable yield of regioisomers of (2-bromotetrafluoroethyl)-trimethoxybenzenes 3 and 4 and small amount of a substitution product of the central trimethoxy group, 1-(2-bromotetrafluoroethyl)-2,6-dimethoxybenzene (5). The reaction...
The regioselective replacement of the 4-methoxy group of 3,4,5-trimethoxybenzaldehyde dimethylacetal by an alkyl group under reductive electron-transfer conditions has been employed as a key step in a new synthesis of 2,5-dialkyl-1,3-dimethoxybenzenes via the corresponding 4-alkyl-3,5-di...
A portion of this product is explained by the combination of Ph2CH+ and 1,3-dimethoxybenzene as the latter accumulates during the irradiation. However, 11.5% of 8 is also seen upon extrapolation to zero time. LFP experiments on the ps time scale reveal that the C2 protonated cation, the 1...
Treatment of 1,2- (or 1,4)-dimethoxybenzene with isobutylene oxide and an appropriate nitrile RCN in concentrated sulfuric acid leads to 1-R-6,7-(or 5,8-)dimethoxy-3,3-dimethyl-3,4-dihydroisoquinolines.doi:10.1070/mc1998v008n01abeh000881Vladimir A. Glushkov...
