Miscellaneous Hydrogenolyses

Primary alcohols with an aliphatic group on the P carbon, such as 2-cyclo-hexylethanol, gave only traces or none of the cleaved products, and the starting materials were recovered. Primary alcohols in which the aromatic nucleus is located on the y carbon rather than the P carbon such as 3-phenyl-1-propanol also did not undergo significant hydrogenolysis. 

3-Diketones are known to be labile to cleavage of carbon-carbon linkages under rather mild conditions, as discussed in Section 5.3.3.
