Process for the production of compounds useful in perfumery.

摘要

Process for producing compounds useful in perfumery including isochromans and acylated indane hydrocarbons by reacting the corresponding substituted benzene with an alkylene oxide or with a lower acyl halide in the presence of a hydrocarbon or hydrocarbon mixture containing C₅ to C₁₀ alkanes at a temperature of at least -20°C; preferably up to -5°C. In the case of forming isochromans, the resulting alcohol is reacted, in situ, with a lower alkanol and a formaldehyde precursor at temperatures of from 20°C up to 80°C.
