The interaction of 1 mol aminoethane acid with 1 mol of allyl chloride and 1 mol of (β-chlor)allyl chloride in an aqueous solution of sodium hydroxide (pH12) leads to the synthesis of the new monomer – N-allyl-N(β-chlor)allylethanic acid (AEA) with a yield of 50%. During polymerization of AEC (T=60-70) in aqueous solution in the presence of ammonium persulfate (PA) initiator with a concentration of 4x10-4- 5x10-3 mol/L, water-soluble polymers with rather high values of reduced viscosity ([ηprid] = 0.18-0.20 dl/g) for the above mentioned amine were obtained. It was established that the polymerization proceeded on the double bonds of diallyl groups according to the cycle-linear mechanism with pyrrolidine stucture.
A study was made of the interaction of thiourea with saturated and unsaturated organosilicon oxiranes in absolute methyl alcohol in a medium of potassium hydroxide, and methods were developed for the synthesis of unsaturated and unsaturated organosilicon silicides with a yield of 65–75%.The studies carried out revealed that the synthesized organosilicon episulfides are very reactive compounds and can react with nucleophilic and electrophilic reagents, while forming the corresponding silicon derivatives. The IR- spectra of the products were studied. It should be noted that, when comparing the IR- spectra of oxiranes and episulfides, it was revealed that the stretching vibrations of the CH2 group of the episulfide ring are underestimated by 50–70 cm-1 in comparison with the oxirane ring
. -Cycloaddition of title allyl-(II) or vinylacetylene alcohols (VI) with tetrachlorocyclopentadiene derivatives (I) proceeds regioselectively at the olefin site to give the propargylic bicycloheptenes (III) and (VII), resp., as endo-adducts. In contrast, both the olefin and alkyne site of the methallylacetylene alcohol (VIII) can act as dienophile in the cycloaddition towards tetrachlorocyclopentadienes (I) to afford a mixture of products (IX) and (X). -(VELIEV*, M.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
