Abstract
9-methoxy-7-nonenal may be isomerized in the presence of methanol and ruthenium chloride to provide 1,1,9,9-tetramethoxynonane. The rates of reaction are increased by pre-formation of 1,1,9-trimethoxy-7-nonene and removal of the water generated prior to conducting the isomerization reaction.
