Abstract

Terpene peroxides of formula: ##STR1## in which R denotes a tertiary alkyl radical substituted, if desired, by one or more phenyl radicals, a cycloalkyl radical or a trialkylsilyl radical, R.sub.1, R.sub.2 and R.sub.3, which are identical or different, each denote hydrogen or an aliphatic radical optionally containing one or more double or triple bonds and optionally substituted, and R.sub.4 denotes an aliphatic radical optionally containing one or more double or triple bonds and optionally substituted or R.sub.3 denotes hydrogen and R.sub.2 and R.sub.4 together form an alkylene radical which may be substituted by one or more methyl radicals, are obtained by reaction of a hydroperoxide of formula R--OOH with a compound of formula: ##STR2## the operation being carried out in a basic aprotic solvent.

Dependent claims

A process for the preparation of a terpene peroxide of formula:

##STR7## in which:
R denotes a tertiary alkyl radical which is unsubstituted or substituted by one or more phenyl radicals, a cycloalkyl radical or a trialkylsilyl radical, R.sub.1, R.sub.2, and R.sub.3, which are identical or different, each denote a hydrogen atom or an aliphatic radical of 1 to 20 carbon atoms which is saturated or contains at least one double or triple bond, and R.sub.4 denotes an aliphatic radical of 1 to 20 carbon atoms which contains at least one double or triple bond, which comprises acting a hydroperoxide of formula:
ROOH
in which R is as hereinbefore defined, with a compound of formula:
##STR8## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as hereinbefore defined and X denotes halogen, alkanoyloxy, alkylsulphonyloxy, arylsulphonyloxy, --ONO.sub.2 or ##STR9## (where R' is alkyl), in a polar aprotic solvent in the presence of an inorganic base at a temperature of between 0.degree. and 50.degree. C.
