Azoperoxides. VI. Selective Decomposition of β‐Azoacylperoxides The selective decomposition of the OO‐Groups in the azoperoxides 1 and 2 is possible by reaction with dimethylaniline at 35°C. Rate constants were measured and the decomposition products were analyzed. Intermediates are azoalkyl radicals. The radical yield of the amine induced decomposition of 2 in ethylbenzene is 8.2% at 35°C. UV irradiation of the azoperoxides 1 and 2 at 20°C in ethylbenzene results in a quantitative and selective decomposition of the azo groups. Intermediates are C‐radicals with intact peroxide groups. The reaction of 1 and 2 with triethylstannane yields reduction products of the OO‐groups and the NN‐groups, respectively.

“…It was also possible to isolate minute amounts of 4-nitro-3,5-dimethylbenzoic acid. 3 The diacetate obtained from the oxidation was easily converted in excellent yields to 4-nitro-3,5dimethylbenzaldehyde by hydrolysis with dilute sulfuric acid.2 Experimental Nitromesitylene4 was prepared. 5 The infrared spectrum6 gave bands at *"¿o1 6.60 initro'NCk) and 7.35 µ (nitro NO2).…”

“…Both requirements are met quite simply by pouring the solution of the Grignard reagent on to dry ice (227, 273). Carbon dioxide under pressure is sometimes required for the preparation of tertiary Grignard reagents (419). By using one or the other of the above techniques 50 to 85 per cent yields of the carboxylic acids have been obtained.…”

example of such a synthesis is the conversion of 2-pentenal, through a Reformatsky condensation with ethyl -bromopropionate and oxalation of the unsaturated product, eventually to 2,6-dimethylsuberic acid (401).It has been shown that formates and oxalates may function as carbonyl components in a Reformatsky synthesis. Ethyl -bromoisobutyrate reacts with ethyl oxalate (569) and with ethyl formate (82), giving hydroxy esters which could be converted to 2,2-dimethylsuccinic and 2,2,4,4-tetramethyIglutaric acids, respectively.The application of the Reformatsky reaction to nitriles (154) leads to the formation of ketones in a manner comparable with the Grignard reaction and is a convenient method for the synthesis of /3-keto esters.By varying the nature of the carbonyl compounds and the halo esters employed, many alkylated dicarboxylic acids have been prepared with the help of this reaction, yet the possible products may be of only a few types. Branching is confined to the a-and ß-positions at one or both ends of the chain, and while the -position may bear one, two, or no alkyl groups, the /3-position cannot bear more than one side chain.Theoretically, in all of the above cases the ester groups of the final products may be converted into aldehyde or keto groups through the acyl chlorides and dialkyl metals (142).A repetition of the Reformatsky process would lengthen the chain with or without further branching at the new points of junction of carbon chains (629).
