4-Benzylidenecyclohexanone → 4-Benzylcyclohexanone

Participants

Reaction Steps

A mixture of 7.15 g (0.031 mole) of 4-benzylidenecyclohexanone, ethylene ketal and 0.35 g of 10% palladium on carbon in 150 ml of ethyl acetate was shaken under hydrogen until the theoretical gas uptake had been observed (1 hour). The catalyst was then removed on a filter and the filtrate was concentrated in vacuo to give 4-benzylcyclohexanone, ethylene ketal as an oil, the nmr spectrum of which agreed with the structure.
