Usage

General Description

P-cyclopentylbenzaldehyde is a chemical compound with the formula C12H14O. It is a versatile building block in organic synthesis, commonly used as a fragrance in perfumes and as a flavoring agent in food. This chemical is an aldehyde, which means it contains a carbonyl group (C=O) bonded to a hydrogen atom and an alkyl or aryl group. P-cyclopentylbenzaldehyde has a pleasant floral odor and is often used to impart a fresh, sweet scent to various consumer products. It is also employed in the production of pharmaceuticals and agrochemicals due to its ability to form key intermediates in the synthesis of complex organic molecules. Additionally, it is used as a precursor in the manufacture of UV absorbers, dyes, and other specialty chemicals.

Synthesis of Certain Mesogenic Azomethines Derived from 4-Cycloalkylanilines and from 4-Cycloalkylbenzaldehydes

General procedures are described for the synthesis of members of five pairs of related homologous series of mesogenic azomethines differing in the mode of linkage of the CH=N group and containing a cycloalkyl group in a terminal position.

Formylation and Acylation Reactions Catalysed by Trifluoromethanesulphonic Acid

Regioselective formylation of toluene, m- and p-xylene, and mesitylene has been achieved by carbonylation in trifluoromethanesulphonic acid at CO pressures of 90-125 atm.In the case of cumene, the formylation reaction is in competition with disproportionation to form di- and tri-isopropylbenzenes, leading to a complex product mixture.Slow addition of cyclohexene or cyclopentene to a mixture of benzene and CF3SO3H under a high CO pressure affords 4-cyclohexylbenzaldehyde and 4-cyclopentylbenzaldehyde in 34percent and 33percent yieds, respectively, while 2-methylbut-1-ene gives 2,2,3-trimethylindanone (39percent) under similar conditions.When cyclohexene is mixed with the acid under carbon monoxide (120 atm) before addition of benzene the major products are cyclohexyl phenyl ketone and cyclohexenyl cyclohexyl ketones.
