One-pot process involving dehydration of cyclohexanol and alkoxycarbonylation of cyclohexene in the presence of catalytic system PdCl2-PPh3-p-toluenesulfonic acid

A one-pot process involving dehydration of cyclohexanol affording cyclohexene followed by alkoxycarbonylation of the latter with cyclohexanol and CO catalyzed by the PdCl 2 -PPh 3 - p -toluenesulfonic acid system was carried out. The yield of the target product, cyclohexyl cyclohexanecarboxylate, wa...

Description
Summary:A one-pot process involving dehydration of cyclohexanol affording cyclohexene followed by alkoxycarbonylation of the latter with cyclohexanol and CO catalyzed by the PdCl 2 -PPh 3 - p -toluenesulfonic acid system was carried out. The yield of the target product, cyclohexyl cyclohexanecarboxylate, was as high as 74.8% after 6 h at 115 °C and at a reactor pressure of 2.1 MPa. In the presence of the offered catalytic system, the process proceeds under mild conditions using available reagents without isolation and purification of the intermediate product, cyclohexene.
