Metallophthalocyanines linked to organic copolymers as efficient oxidative supported catalysts

The covalent anchoring of metallo(chlorosulfonyl)phthalocyanines 1 onto the acrylic copolymers 2 and 3 has been achieved. When using H2O2 or KHSO5 as oxidant, these supported catalysts are able to oxidize a poorly biodegradable molecule such as 2,4,6-trichlorophenol or a tannin model such as 3,5-di-tert-butylcatechol. The influence of the spacer and the nature of the reaction medium on the catalytic activities have been studied, as well as the recycling of these supported metallophthalocyanine catalysts.

Key role of the phosphate buffer in the H2O2 oxidation of aromatic pollutants catalyzed by iron tetrasulfophthalocyanine

The non-innocent role of the phosphate buffer has been established in the H2O2 oxidative decomposition of 2,4,6-trichlorophenol (TCP), a benchmark pollutant, catalyzed by iron(III) tetrasulfophthalocyanine (FePcS). The catalytic oxidation of several other substrates (3,5-dichloroaniline, tetrachlorocatechol, di-tert-butylcatechol and catechol itself) has been carried out, also demonstrating a crucial influence of the phosphate buffer in the decomposition of the chlorinated substrates. Three hypotheses have been studied: modification of the ionic strength, formation of a peroxyphosphate species, or catalysis by a peroxyphosphate-FePcS complex. Supports for the latter proposal have been obtained from several experimental results and attempts have been made to characterize this putative catalytic intermediate. This intermediate derivative has also been generated from the reaction of FePcS with peroxymonophosphoric acid (PMPA) and its catalytic activity has been checked on the decomposition of TCP in different reaction mixture. A short mechanistic study has allowed different reaction pathways to be proposed, dependent on the active species implicated.

STEREOCHEMICAL COURSE OF THE ENZYMATIC AMINATION OF CHLORO- AND BROMO- FUMARIC ACID BY 3-METHYLASPARTATE AMMONIA-LYASE

Enzymatic amination of chloro- and bromo- fumaric acid using 3-methylaspartate ammonia-lyase in the presence of ammonia leads to the formation of 3-chloro- and 3-bromo-aspartic acid respectively; the absolute configuration of each product is (R) at C-2 and (S) at C-3.

SYNTHESIS AND SOME REACTIONS OF 1,1,3,4,4-PENTACHLORO-1,3-BUTADIENE-2-SULFONYL CHLORIDE

The direct chlorosulfonylation of polychlorodiene systems was realized for the first time for the case of the reaction of 2-H-pentachloro-1,3-butadiene with chlorosulfonic acid.A series of 1-alkyl(aryl)amino-1,3,4,4-tetrachloro-2--1,3-butadienes were synthesized by the reaction of the obtained 1,1,3,4,4-pentachloro-1,3-butadiene-2-sulfonyl chloride with amines.
