Ring-opening of alkyl-substituted cyclopropanes in the presence of hydrogen on copper
Abstract
In the presence of hydrogen on copper, the cyclopropanes (1), (2), and (3) are transformed into saturated hydrocarbons containing the same number of carbon atoms (alkenes are also formed, through isomerization of the cyclopropanes); these studies reveal the importance of a previously unknown property of copper in heterogeneous metal catalysis.
