Ni-Cu/Al2O3 containing O.1percent CeO2: A New Catalyst for Dehydrogenation of Alcohols
A highly active and selective catalyst containing 10percent Ni-Cu (atomic ratio 7 : 3) supported on alumina and promoted with 0.1percent cerium oxide was developed for dehydrogenation of secondary alcohols into corresponding ketones in vapour phase.

THE CHEMISTRY OF 1,3,4-THIADIAZOLINE-2-SPIRO-2'-FENCHANE.
Diazomethane adds to one of the two faces of the sterically hindered thiofenchone furnishing the title compound wich extrudes N2 at 46 deg C whith t1/2=22 min; the thiofenchone S-methylide is intercepted by dipolarophiles and acts as a base in reactions with methanol, thiophenol and acetic acid, in the latter case accompanied by skeletal rearrangement.
