- This agent comprises or consists of a persulfate and one or more transition metals, the latter (s) being present (s) in elemental form or in oxidized form.
- said transition metal behaves as an efficient co-initiator of a persulfate in a radical addition reaction, in a range of temperatures close to room temperature.
- This discovery makes it possible to resolve the selectivity problem linked to the use of persulfate which, in order to be active, must intervene in a heated reaction medium, such conditions resulting in an inevitable loss of selectivity.
- the persulphates can be replaced in certain cases by organic peroxides depending on the objective sought and the constraints on the quality of the reaction product and the effluents of the process.
- This initiator and its advantages are in the remainder of the text more specifically set out in the context of a radical addition reaction of a thiol, a disulfide, a selenol, a diselenide or an alcohol on a vinyl compound such as a compound of formula (III) shown below. It is of course not restricted thereto, and the invention relates to such an agent which can be used for any radical addition reaction of a thiol, a disulfide, a selenol, a diselenide or d an alcohol, on a compound carrying a double bond which is unconjugated, and which is terminal or not. This agent is particularly advantageous when a high selectivity is expected.
- persulfate breaks down pollutants into harmless small molecules like CO 2 , water and sulfates.
- persulfate breaks down pollutants into harmless small molecules like CO 2 , water and sulfates.
- it is used in the form of aqueous solutions at a concentration of approximately 5% and rapidly generates radicals after activation, some of which have a powerful oxidizing power. It acts on several types of polluting compounds, mainly hydrocarbons, the degradation of which generates various small-sized products.
- persulfate is meant the oxyanion S 2 O 8 2 , or its salt formed with any counterion.
- organic peroxide any organic species of formula R 7 -OOR 8 with R 7 and Rs, which may be identical or different, being chosen from H, alkyl groups, aryl groups, alkylaryl groups and CO — R 1 groups where R 1 is as defined below.
- a radical addition reaction responds to a chain reaction mechanism comprising an initiation which takes place from an initiating agent, a propagation which sees the radical (s) formed during the initiation react with a compound then the termination.
- elemental form of a metal is meant a metal with oxidation degree 0, or otherwise expressed, a metal in its reduced form.
- oxidized form of a metal we include any association of a metal with one or more anions or with oxygen, at any degree of oxidation of the metal. Included in this definition are oxides, sulphates, phosphates, chlorides (eg FeCU), carbonates, hydroxides, nitrites, nitrates, acetates, alcoholates, hydrogen phosphates and hydrogen sulphates.
- alkyl denotes a linear or branched monovalent hydrocarbon radical having from 1 to 20 carbon atoms, advantageously from 1 to 6 carbon atoms, such as methyl or ethyl , propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, neopentyl, n-hexyl or a cyclic monovalent hydrocarbon radical having from 3 to 20 carbon atoms, advantageously from 3 to 6 carbon atoms, such as cyclopropyl, cyclohexyl.
- aryl group is understood to mean an aromatic monovalent hydrocarbon radical comprising from 6 to 22 carbon atoms.
- alkylaryl group is meant an aryl group comprising from 6 to 22 carbon atoms, said aryl group being substituted by at least one alkyl group corresponding to the definition above.
- the invention relates to the application of an agent for the initiation, or initiating agent, or initiating agent, in a radical addition reaction, said agent comprising or consisting of a persulfate and one or more transition metals, under elemental form or in an oxidized form.
- the persulfate may be in the form of a salt of a cation, the associated cation preferably being chosen from sodium, potassium, calcium, lithium and ammonium ions, although any counterion may be suitable.
- the persulphates can be, in certain cases, advantageously replaced by organic peroxides.
- Persulfate can be combined with one or more transition metals.
- the mixtures can consist of the same metal in the elemental state and / or in different degrees of oxidation; different metals in the elementary state and / or in the same degree of oxidation or in different degrees of oxidation, but also in the form of alloys such as for example brass, optionally in oxidized form.
- the transition metal (s) are advantageously chosen from Cu, Zn and Fe, in their elemental form or in an oxidized form as defined above.
- the molar ratio of persulfate to the transition metal (s) ranges from 0.5 to 10,000.
- An excess of metal can lead to a drop in the selectivity of the reaction, but a too low content will slow down the reaction, affecting its industrializable interest.
- this molar ratio ranges from 1 to 1000.
- the aforementioned combination of a persulfate and one or more transition metals is applied to the initiation of a radical addition reaction involving an organic entity capable of forming a radical which reacts on a double bond .
