Aroma Chemicals from Alkyl Halides

The substitution of akyl halides hy zinc salts thus constitutes a very useful synthetic reaction for the preparation of alcohols, ethers, esters, thioethers and thiolesters both under solvolytic and nonsolvolytic conditions. Using this versatile reaction, a large number of allyl, benzyl and tertiary alkyl derivatives, which are widely used in the perfumery and flavour industry, can be obtained. Among these, mention must be made of a-terpinyl, l-menthanyl, myrcenyl, dihydromyrcenyl, benzyl, styrallyl 3,3-dimethyhdlyl and carvyl esters, ethers and alcohols. The inexpensive reagents, convenient reaction conditions and suitability for large-scale operation are attractive features of the method.
