    Description / Table of Contents: Reductive Removal of Phenolic Hydroxy Groups, 2. Hydrogenolytic Cleavage of O-Aryl-N,N-dialkylisoureasPhenols are converted into aromatic hydrocarbons under mild conditions and in good yields by catalytic hydrogenation of their corresponding O-aryl-N,N-diethylisoureas. Benzene and anilin are formed from p-chlorophenol and p-nitrophenol respectively. The reductive cleavage is sensitive to sterical factors.
    Notes: Phenole können über die O-Aryl-N,N-diäthylisoharnstoffe unter milden Bedingungen und mit sehr guten Ausbeuten hydrogenolytisch in die entsprechenden aromatischen Kohlenwasserstoffe übergeführt werden. Im Falle von p-Chlorphenol bzw. p-Nitrophenol werden Benzol bzw. Anilin erhalten. Die reduktive Spaltung ist gegen sterische Faktoren empfindlich.
