Sodium S-[3-(hydroxyaryl)propyl] thiosulfates and [3-(hydroxyaryl)propane]- 1-sulfonates with various spatial hindrance of their phenolic OH groups were synthesized from dialkylphenols via a number of intermediate products. On a model reaction of oxidation of methyl oleate in aqueous sodium dodecyl sulfate, the rate constants of the interaction of the synthesized compounds with lipoperoxide radicals were determined.

The Claisen rearrangement of allyl phenyl ethers is a fundamental reaction in organic synthesis with a variety of applications in perfumes, flavors, pharmaceuticals, agrochemicals, polymers, fine chemicals, and intermediate industries. The development of environmentally benign processes using solid acid catalysts is becoming an area of growing interest. It was accomplished in an efficient, economical, environmentally friendly manner and is 100% selective toward alllyl phenols by employing UDCaT-5 as solid acid catalyst.

Use of modified diorganopolysiloxanes as antioxidants in cosmetics or in dermatology. Use, as an antioxidizing agent in cosmetics or in dermatology, of diorganopolysiloxanes (i) of formula (I): STR1 in which the symbols R denote alkyl or phenyl, B are chosen from the radicals R and A, a an integer chosen between 0 and 200 inclusive, b an integer chosen between 0 and 50 inclusive, and if b is equal to 0, at least one of the two symbols B is A, A is of formula: STR2 where: R1 denotes hydrogen or an alkyl, R2 denotes hydrogen, hydroxyl, alkyl or alkoxy, R3 denotes hydrogen, hydroxyl or alkyl, R4 denotes hydrogen or alkyl, R5 denotes hydrogen, hydroxyl or alkoxy, Y denotes: where R6 denotes hydrogen or alkyl and n has the value of 0 or 1, or (ii) of formula (II): STR3 where c is an integer between 1 and 20 inclusive, d is an integer between 2 and 20 inclusive, and c+d equal to or greater than 3.
EFFECT OF METAL IONS IN ORGANIC SYNTHESIS. XXXV SIMPLE AND CONVENIENT AROMATIC ALKYLATION OF SOME ALKENYLPHENOL DERIVATIVES WITH tert-ALKYL METHYL ETHERS IN THE PRESENCE OF TIN(IV) CHLORIDE
Attanasi, Orazio A.,Filippone, Paolino,Balducci, Sandro
, p. 487 - 489 (2007/10/02)
A very mild, simple and convenient method for the aromatic alkylation of some alkenylphenol derivatives with tert-alkyl methyl ethers to give sterically hindered phenols useful as antioxidants is reported.The reaction occurs with good yields at room temperature and is promoted by tin(IV) chloride.
