Applicazioni

It is an important raw material and intermediate used in organic synthesis, dyestuffs and in agrochemical industries. It is used in medicine. Cyclohexene oxide (epoxycyclohexane) is an useful monomer in polymerization and coating industry. It is used in the synthesis of alicyclic target materials including pharmaceuticals, perfumery and dyestuffs. It is used as a monomer in photopolymerizations, with carbonmonoxide to yield aromatic polycarbonates which has minimum impurities.

Note

Store at room temperature. Incompatible with oxidizing agents.

A general method for the conversion of epoxides to cis-dichloro alkanes, with inversion at both centers, by reaction with triphenylphosphine dichloride, has been exemplified: Org. Synth. Coll., 6, 424 (1988).

Rearrangement to cyclopentanecarboxaldehyde is catalyzed by LiBr on alumina, either by refluxing in toluene or in the gas phase: Synthesis, 394 (1988). An alternative isomerization to the allylic alcohol is induced by base catalysis. Optimized conditions use a mixture of KO-t-Bu and 2.5 equivalents of LDA: Tetrahedron, 46, 2411 (1990). For discussion of the mechanism, see: J. Org. Chem., 61, 820 (1996), and references therein. For a review of the rearrangement of epoxides to allylic alcohols, see: Org. React., 29, 345 (1983).

A general method for the synthesis of ɑ-chloro carbonyl compounds is illustrated by the reaction of cylohexene oxide with the Swern reagent (DMSO/ oxalyl chloride) to give 2-chlorocyclohexanone in 93% yield: Tetrahedron, 51, 2467 (1995).
