B(C6F5)3-Catalyzed Highly Stereoselective Hydrogenation of Unfunctionalized Tetrasubstituted Olefins

A metal-free hydrogenation of unfunctionalized tetrasubstituted olefins were successfully realized using a combination of B(C6F5)3 and Ph2NMe catalyst. The corresponding products were afforded in 58-98% yields with up to >99:1 cis/trans selectivity.

SYNTHESIS OF INDENES FROM PHENYLPROPANONES USING ALUMINA CATALYST

1,3-Diphenylpropan-2-one undergoes dehydration over alumina at around 400 deg C to form 1,3-diphenylallene which cyclizes to 2-phenylindene.Since the parent ketone can be obtained under the reaction conditions from phenylacetic acid, the present reaction forms a one step syntheses of 2-phenylindene from phenylacetic acid. 3- and 4-methylphenylacetic acids also give the corresponding indenes. 1,3-Diphenylpropan-1-ones also give phenylindenes, presumably by a direct cyclodehydration reaction.
