Diallyl oxalate

Attempts with (MeCN)3Cr(CO)3 meet with no success. For Mo (but not W) Mo(CO)g can be used in acetonitrile, as acetonitrile displaces CO at reflux, and the intermediate (MeCN)3Mo(CO)3 reacts at RT. In alcohols (or acetonitrile), Mo(CO)j reacts at reflux temperature with diallyl oxalate to form XIII in excellent yields ... 

Whereas monoallyl derivatives sdeld thermoplastic polymers, allyl esters containing two or more unsaturated groups yield thermosetting resins. Thus, monoallyl esters of unsaturated acids, e.g., allyl acrylate, allyl methacrylate, allyl crotonate, and allyl itaconate, and diallyl esters of dibasic acids, e.g., diallyl oxalate, diallyl phthalate, and diallyl itaconate, yield thermoset resins, which generally combine solvent resistance, toughness, hardness, transparency, and heat resistance. The cross-linking tendency of the allyl esters makes them useful in copolymerization wherein they impart these properties to normally linear polymers. 

Allyl radicals were tested as materials or substances that cause cyclization with olefins. 1,5-Hexadiene (diallyl) and diallyl oxalate (DAO) were used as the source materials for allyl radicals. These compounds were subjected to the thermal reaction in the presence of ethylene, which resulted in a rapid formation of five-membered cyclic compounds. The role of allyl radical for the formation of aromatics in pyrolysis reaction is however still... 

A summary of rate data is given for the systematic study of the formation of cyclic compounds during thermal reactions of olefins or of olefins with butadiene. As a next step in order to investigate cyclization at pyrolysis conditions, the reactions of allyl radicals with olefins were studied kinetically. 1,5-Hexa-diene (diallyl) and diallyl oxalate (DAO) were employed as source... 

Because of the ease of synthesis and industrial importance of diallyl esters much of the research has dealt with the behavior of the isomeric phthalates. Some other dicarboxylic acid esters have been studied by Simpson and Holt [41]. The kinetics of the poljmierization of the diallyl esters of oxalic, malonic, succinic, adipic, and sebacic acid have also been considered. In previous kinetie studies, no differentiation was made between the behavior of the uncyclized monomer (or its free radical) and of the cyclic free-radicals. A priori, differences should have been presumed, but evidently Matsumoto and Oiwa [46] were the first seriously to attempt a kinetic analysis based on the concept that the linear and the cyclic units are two different species. In effect, these two species copolymerize with each other. However, the analysis has not been carried so far as to determine reactivity ratios.
