Mono- or difluorinated hydrocarbon compounds are prepared from an alcohol or a carbonylated compound by reacting one of these with a fluorinating reagent, optionally in the presence of a base, the fluorinating agent comprising a pyridinium reactant having the following formula (F), wherein R
0
is an alkyl or cycloalkyl radical:
The invention relates to new terpene ethers of the formula ##STR1## in which R denotes a cyclic or bicyclic radical or an alkyl radical which is substituted by cyclic, bicyclic or tricyclic radicals, optionally via an oxygen bridge. The compounds are prepared by reaction of camphene with alcohols R--OH, in which R represents one of the above-mentioned radicals. The new ethers are used in the field of aroma substances and solvents, and as intermediates for plant protection agents, agents for combating pests and medicaments.
