main products in moderate to good yields. The head-to-head regioselectivity in reductive coupling of 4-penner-1-ol and 5-hexen-2-ol was also observed. Coupling of 2-methyl-5-hexen-2-ol, as well as unsaturated alcohols in which vinyl and hydroxyl groups are more distant from one another, proceeded with head-to-tail or tail-to-tail regioselectivity. It is supposed, that the unusual head-to-head regioselectivity

Compounds containing unsaturated aliphatic moieties which are linked to each other by a tertiary oxycarbonyl containing acyclic moiety are basis for compositions which are cured to polymer networks which are thermally decomposable to provide residue which can be dissolved to allow repair of inoperative assemblies by replacement of inoperative components or recovery or recycling of operative elements which are affixed in assemblies by the cured compositions.
