[4+2]-CYCLOADDITION REACTION OF 1-ACETOXYHEXEN-5-YN-2 TO POLYCHLOROCYCLOPENTADIENES AND HYDROSILYLATION OF THE PREPARED ADDUCTS
It has been shown that 1-acetoxyhexen-5-yn-2 undergoes the diene synthesis reacion with hexacloro- and 5,5-dimethoxytetrachlorocyclopentadienes at 125-130°C due to the end double bond with formation of endo izomers. The synthesized adducts undergo the interaction with triorganosilanes in the presence of H2PtCl6.6H2O in medium of benzene. The reaction proceeds on triple bond but with preferential yield (77–99%) of β-adduct (relatively oxygen atom)
