cymene , auch: cymol

It is the type of the terpenes and is related to cymene.

His group first prepared the now popular reagent (cymene)ruthenium dichloride dimer.

This is distilled to dryness and the distillate repeatedly recrystallized from cymene.

Among the terpenes most toxic to flea larvae in the bay leaves are umbellelone, cineole, and cymene.

A representative catalyst precursor is derived from (cymene)ruthenium dichloride dimer and the tosylated diphenylethylenediamine.

Upon heating, [(cymene)RuCl] undergoes exchange with other arenes, releasing free p-cymene.

When reacted with sulfuric acid, or reduced with zinc powder and acetic acid, ascaridole formed cymene.

One example of an Ru-arene complex is (cymene)ruthenium dichloride dimer, which is the precursor to a versatile catalyst for transfer hydrogenation.

Many half sandwich complexes of ruthenium, such as those derived from (cymene)ruthenium dichloride dimer catalyse transfer hydrogenation, a useful reaction in organic synthesis.

Half-sandwich compounds employing Ru(II), such as (cymene)ruthenium dichloride dimer, have been mainly investigated as catalysts for transfer hydrogenation.

In the cymene-cresol process, phenol is alkylated with propylene to give isomers of cymene, which can be oxidatively dealkylated (Hock rearrangement) analogous to the cumene process.

(Cymene)ruthenium dichloride dimer is the organometallic compound with the formula [(cymene)RuCl].

Terephthalic acid can be prepared in the laboratory by oxidizing various para-disubstituted derivatives of benzene, including caraway oil or a mixture of cymene and cuminol with chromic acid.

For example (cymene)Ru(S,S-TsDPEN) catalyzes the hydrogenation of benzil into R,R-hydro benzoin.

While with Hofmann he made researches on the oxidation of cymol or cymene, the hydro-carbon which Gerhardt and Cahours discovered in 1840 in the volatile oil of Roman cumin.
