Perseleninic acids, as oxidizing agents 240 Persulphenates 709 Persulphoxides 709 Perturbation 1050 Peterson reaction 332 Phase transfer catalysis 573-575, 985, 986, 990... 

In addition to the synthesis of saccharin, also a number of other side-chain oxidations have been studied leading to aromatic carboxylic acids by indirect electrochemical oxidation using chromic acid as oxidizing agent. They include the oxidation of p-nitrotoluene 2,4-dinitrotoluene toluene, p-xylene, and p-tolualdehyde... 

In addition to selenoxides and seleninic acids as oxidation agents, diethyl selenite (109) was reported as the first efficient oxygen transfer reagent. Namely, it was found [48] that diethyl selenite (109), easily prepared by the reaction of selenium dioxide with ethanol [54], is able to convert selected... 

The compound could not be oxidized to a tellurone using hydrogen peroxide, sodium periodate, or 3-chloroperoxybenzoic acid as oxidizing agents ... 

In comparison with the standard system for epoxidation which uses m-ehloro-peroxybenzoic acid as oxidizing agent, the MTO/H202/aromatic Lewis base system displays several advantages (a) it is safer but equal in price (b) due to the suppression of epoxide ring opening, it has a much broader scope (c) its selectivity is higher, and (d) it is more reactive, requires less solvent, the product work-up is easier, and the only by-produet formed is water. 

Application of nitric acid as oxidizing agent for this purpose is restricted mainly to aliphatic sulfides because of possible nitration.613... 

The free amine cannot be converted directly into the acid, as oxidizing agents destroy the amino group in general, such groups are protected when a compound containing them is to be oxidized. 

Application of 2-iodoxybenzoic acid as oxidizing agent in organic synthesis 06CJO1623. 

A process developed by Bergbau-Forschung recommends dilute nitric acid as oxidizing agent (Figure 8.1). 

Mild and selective oxidation of aryl halides to corresponding aldeliydes using iodoxybenzoic acid as oxidizing agent and IL has been reported [145]. An efficient oxidation of benzyl halide was reported [146] using aqueous hydrogen peroxide (30%) in trihexyl(tetradecyl)phosphonium-tetrafluroborate IL the protocol is simple and mild offering excellent yield of product. 

Acids as Oxidant Agents. The reaction of metal clusters with oxidant acids such as nitric or sulfuric acids often produces cluster breakdown leading to salts of the metals in higher oxidation states. 

The reaction considered was the catalytic oxidation of ethyl alcohol, dissolved in an aqueous alkaline solution, to acetic acid As oxidizing agent gaseous oxygen was used The catalyst employed was 0 5% Pd supported on alumina Table 5 gives the properties of the catalyst A previous kinetic study was carried out to measure the intrinsic chemical kinetic parameters of this reaction For this purpose a tubular, packed, flooded reactor was used (oxygen was supplied after its absorption in the solution before entering the reactor) Papers on this subject have already been published Baldi et al [2], [3] ...
