Thermal C-H Activation Catalyzed by RhCl(CH2=CH2)(PMe3)2. Hydrogen Transfer from Cycloalkanes to Ethylene and Ethylene Insertion into Cycloalkanes

Dehydrogenation of cycloalkanes to cycloalkenes is catalyzed by RhCl(CH2=CH2)(PMe3)2 under ethylene pressure at a high temperature over 170 deg C.Ethylene insertion into sp3 C-H bond of cycloalkanes occurs at 230 deg C to afford ethylcycloalkanes.

Dependent on n different products are obtained from bicycloalkanes by hydrogenation on Pt and Pd/C catalysts: from n = 5 onward only methylcycloalkanes of the same ring size; with n = 4 additionally 2-7 percent of cycloheptane is formed; with n = 3 ring enlargement increases to 5-20 percent and with n = 2 cyclopentane is the only product.Mainly butane is formed from bicyclobutane and no intermediate could be detected.Explanations are attempted.The expected products are produced on hydrogenation of methyl-substituted derivatives and spiroalkanes.
