Hydrolysis in the presence of alkali does lead to benzyl alcohol, however. Benzyl chloride reacts with sodium cyanide to give phenylacetonitrile (benzyl cyanide). Reaction with ammonia or amines gives primary, secondary, tertiary amines, and quaternary ammonium salts. The reaction with hexamethylenetetr...

4.1.Hydrolysis of Benzyl Chloride The hydrolysis of benzyl chloride is a reversible reaction which leads to the almost quantitative formation of benzyl alcohol only in the presence of alkaline saponifying agents that combine with the hydrogen chloride as it is formed. It is there-fore carried out...
An epoxidation of the C-5–C-6 double bond of 73, followed by the hydrolysis of the oxirane ring in 76a and 76b, gives pyriculariol (64). A reduction of the aromatic aldehyde 64 affords dihydropyriculariol (65). Similarly, a fermentation by a shaking culture allows the epoxidation of...

(5) Closely related functional groups: Aromatic sulfonyl fluorides are significantly more resistant to hydrolysis than aliphatic derivatives with α-hydrogens, and electron-withdrawing groups on the aromatic ring enhance the electrophilic nature of S (VI) and speed up its reactivity [65]. Sulfony...
synthetic method from benzyl chloride and sodium hydroxide. In the case of a chemical synthetic method, benzyl chloride (synthetic benzyl chloride) is prepared by a Grignard reaction and then benzyl alcohol is obtained from the synthetic benzyl chloride through reduction, hydrolysis, and dehydrogenation...
