In the benzene bromination reaction, HZSM-5 (Si/Al = 400/1) was found to be a stable catalyst, which catalyzed the stoichiometric reaction of benzene with bromine. More than 90% of bromobenzene selectivity was reached over HZSM-5 and the byproduct was dibromobenzenes. In the second ...
Benzene reacts (1) with chlorine, to form (a) substitution products (one-half of the chlorine forms hydrogen chloride) such as chlorobenzene, C6H5Cl; dichlorobenzene, C6H4Cl2(1,4) and (1,2); trichlorobenzene, C6H3Cl3(1,2,4); tetrachlorobenzene (1,2,3,5); and (b) addition produc...

Nitration of Benzene: Benzene reacts with nitric acid at 323-333 K in the presence of sulphuric acid to form nitrobenzene. This reaction is known as nitration of Benzene. Sulphonation of Benzene: Sulphonation of benzene is a process of heating benzene with fuming sulphuric acid (H2SO4+SO3)...
1-BROMO-4-DIFLUOROMETHYLBENZENE, with the chemical formula C7H5BrF2 and CAS registry number 51776-71-7, is a compound known for its applications in various chemical processes. This colorless liquid, also referred to as 1-Bromo-4-difluorotoluene, is characterized by its bromine and difluoro...
Hantzsch esters like (7b) react with appropriate acceptors to provide reduced product and pyridine (75), as shown in equation (32). The elements of hydrogen are transferred, but there are no effective ways to transform (75) cleanly back to (7b) so that a catalytic cycle may be established...
“green production” in the petrochemical and detergent industry. A lot of papers and patents have been published using chloroaluminate ionic liquid as a novel catalyst for alkylation with high reactivity and easy separation from reactants. These included the acidity, characterization, determination and...
carbon,thus forming a carbonium ion.The carbonium ion further reacted with benzenes to form a complex.Due to unstabilit of the complex,a deuterated ring proton was transferred into an electronegative 1-carbon of the side chain to substitute for the AlCl3,accordingly 2-phenyldodecane was ...
2.A process for producing a benzene derivative having a long, linear conjugated structure represented by general formula (1):(wherein R1and A represents an alkylene group), the process comprising the steps of: allowing 4-hydroxybenzaldehyde represented by general formula (2):to react with a halo...
A 7- or 8-methoxy-chroman or -chromanone (678) reacts in the Vilsmeier–Haackformylationto give the 6-carboxaldehyde; 8-hydroxychroman is acylated with acetic acid–boron trifluoride largely at C-7 but the same reagent converts 8-methoxychroman into the 6-acetyl derivative〈81HC(36)251〉....
