The copolymerization of 2-methylenespiro-orthoesters with maleic anhydride and with maleimides has been studied. The reaction takes place by a radical mechanism with the formation of copolymers with a 1 : 1 composition and a strictly alternating stru

It is shown that the catalytic and thermal rearrangements of cyanuric acid triallyl esters to isocyanuric acid esters proceed via inter- and intramolecular mechanisms. Cross-reaction products are formed when the reaction is carried out with a mixture

We have studied the kinetics and the products of the thermal degradation of acetylcyclohexylsulfonyl (I), dibenzyl (II) and dicyclohexyl peroxide carbonate (III) in various solvents. The kinetic data show that the degradation is first-order with resp

The oxides of ethylene and propene, and epichlorohydrin, react with thionylanilines (ArN=S=O) in the presence of tetraethylammonium bromide catalyst at 95°–100° C to give N-arylalkeneamidosulfites, whose structures are confirmed by retrosynthesis

It is shown that the direction of chlorination of 1,3-dioxolan-4-ones in the presence of benzoyl peroxide is determined by the nature of the substituent at the 5-position of the ring. In this case a chloromethyl group, having a —I effect, promotes

On reaction with N-phenylethyleneimine in the presence of tetraethylammonium bromide, methyl and phenyl isothiocyanates form 2-methyl- and 2-phenyl-imino-3-phenylthiazolidines. In this reaction, methyl isothiocyanate partially trimerizes. Under the a
