PTC Reaction of the Month - Selective Hydrogenation
Even though the reaction shown below was reported long ago, many of our customers and ourselves find it very intriguing that it may be possible to reduce the aromaticity while leaving the carbonyl intact. The yield reported for benzene to cyclohexane is also 100%. Januszkiewicz, K.; Alper, H.; Organometallics, 1983, 2, 1055
