Diene condensations of hexachlorocyclopentadiene and 5,5-dimethoxytetrachlorocyclopentadiene were carried out with dienophiles of allylacetylene series. The reaction was demonstrated to proceed stercospecifically yielding adducts of the endo-configuration. The reactivity of functionalized allylacetylene compounds in the diene synthesis with hexachlorocyclopentadiene was studied, and the reaction was established to occur by the type of a "neutral" diene synthesis. It was established that the Faworsky decomposition of polychlorobicyclic alcohols containing in the side chain a triple bond adjacent to a methylene group occurred with acetylene-allene isomerization.
Allylacetylenes and their derivatives as inhibitors of steel corrosion in sulfuric acid
摘要:
New functionalized derivatives of allylacetylenes were prepared, and their ability to inhibit corrosion of St.3 low-carbon steel in 5 N sulfuric acid was studied. The effectiveness of inhibition of steel corrosion was studied in relation to the structure of acetylene derivatives, their concentration, and temperature of acidic medium.

Diene condensation of cyclopentadiene with 2-substituted allylacetylenes occurs nonselectively at a double and triple bonds; therewith the dienophile activity grows in parallel with the electron-withdrawing properties of the substituent. Depending on electronic character of functional groups the reaction proceeds as ''neutral" diene synthesis. The relative activity of cyclopentadiene and 1,3-cyclohexadiene in reactions with allylacetylenes is essentially governed by the different distance between the 1,4-reactive sites in these systems.
