Usage

Description

(Cyclohexyl-phenyl-methyl)benzene, also known as ethylbenzene, is a colorless liquid with a strong, aromatic odor. It is a chemical compound that is primarily used in the production of styrene, which is a precursor to a wide variety of plastics and synthetic rubber.

Uses

Used in Plastics and Synthetic Rubber Industry:
(Cyclohexyl-phenyl-methyl)benzene is used as a precursor for the production of styrene, which is then used to manufacture various types of plastics and synthetic rubber. This makes it an essential component in the creation of a wide range of products, from packaging materials to automotive parts.
Used as a Solvent in Manufacturing:
(Cyclohexyl-phenyl-methyl)benzene is used as a solvent in the production of inks, adhesives, and paints. Its solvent properties allow it to dissolve and mix with other substances, making it a valuable component in the manufacturing process of these products.
However, it is important to note that (cyclohexyl-phenyl-methyl)benzene is classified as a hazardous substance. Exposure to high levels of ethylbenzene can have harmful effects on the central nervous system, liver, and kidneys. Therefore, it is crucial to handle and store (cyclohexyl-phenyl-methyl)benzene with caution to minimize the risk of exposure and potential health hazards.

SN2 Reaction of Diarylmethyl Anions at Secondary Alkyl and Cycloalkyl Carbons

The substitution reaction of the diethyl allylic and propargylic phosphates with Ar2CH anions was applied to sec-alkyl phosphates to compare reactivity and stereoselectivity. However, the substitution took place on the ethyl carbon of the diethyl phosphate group. We then found that the diphenyl phosphate leaving group ((PhO)2PO2) was suited for the substitution at the sec-alkyl carbon. Enantioenriched diphenyl sec-alkyl phosphates with different substituents (Me, Et, iPr) on the vicinal position underwent the substitution reaction with almost complete inversion (>99% enantiospecificity). The substitution reactions of cyclohexyl phosphates possessing cis or trans substituents (Me and/or tBu) at the C4, C3, and C2 positions of the cyclohexane ring were also studied to observe the difference in reactivity among the cis and trans isomers. A transition-state model with the phosphate leaving group ((PhO)2PO2) in the axial position was proposed to explain the difference. This model was supported by computational calculation of the virtual substitution reaction of the structurally simpler “dimethyl” cyclohexyl phosphates (leaving group = (MeO)2PO2) with MeLi. Furthermore, the calculation unexpectedly indicated higher propensity of (PhO)2PO2 as a leaving reactivity than alkyl phosphate groups such as (MeO)2PO2 and (iPrO)2PO2.

Modern Friedel-Crafts chemistry. Part-271. Alkylation of benzene with 1-benzyl- and 1-phenylcyclohexanols in the presence of H 2SO4 and AlCl3/CH3NO2 catalysts

The alkylation of benzyene with 1-benzylcyclohexanol (3) gave a mixture of 2,3-benzobicyclo[3.3.1]nona-2-ene (8, 79%) and cyclohexyldiphenylmethane (10, 21%) with AlCl3/CH3NO2 catalyst and a mixture of 1-benzylcyclohexene 5 (47.5%), 8 (8%), 10 (21.5%), 1-cyclopentyl-1,2- diphenylethane (12, 18%) and 1-benzyl-1-phenylcyclohexene (13, 4%) with H 2SO4 catalyst. Treatment of 3 with AlCl 3/CH3NO2 in petroleum ether gave a mixture of 5 (26%) and 8 (62%). Attempted alkylation of benzene with 1-phenylcyclohexanol (4) in the presence of either AlCl3/CH3NO2 or H2SO4 catalyst gave 1-(1-phenylcyclohexyl)-2- phenylcyclohexene (17) as sole product. Mechanistic interpretation of the results in terms of carbocation behaviour is offered.
