SYNTHESIS OF ENYNES ON THE BASIS OF HEXEN-5-YN-2-OL-1
The diene synthesis reaction of hexen-5-yn-2-ol-1 and its some functionally substituted derivatives with hexachloro- and 5,5-dimetoxytetrachlorcyclopentadienes in a medium of m-xylol at 125–1300C has been investigated. It has been shown that the reaction proceeds by mechanism of [4+2]-cycloaddition due to end double bond with formation of endo-adducts. A yield is 86–95%
Keywords : hexen-5-yn-2-ol-1, hexachlorocyclopentadiene, 5,5-dimethoxytetrachloro¬cyclopen¬ta¬diene, m-xylol, diene synthesis, endo-adduct
