Question

A stereoselective form of these reactions involves cis-di•imide. A family of selective first-row transition metal catalysts for these reactions is named for Urushibara. (15[1])One of these reactions with an amine catalyst uses Hantzsch ester. One of these reactions featuring tetralin as the “donor solvent” is used to liquefy coal, exemplifying these reactions’ (*) “transfer” type. (10[1])The 2001 Nobel Prize in Chemistry was awarded for an enantioselective (-5[1])form of these reactions used to synthesize L-DOPA by Knowles. (10[1]-5[1])Using a BINAP-ruthenium catalyst in these reactions was pioneered by Noyori. (10[1])Palladium is a common catalyst for these reactions, which may see cis-trans interconversion when only partial. For 10 points, name these reactions exemplified by the conversion of an alkene to an alkane. ■END■ (10[1]0[1])

ANSWER: hydrogenation [or transfer hydrogenation; or asymmetric hydrogenation; prompt on hydrogen transfer before “transfer”; prompt on reduction; reject “dehydrogenation”]
