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. 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. The 2001 Nobel Prize in Chemistry was awarded for an enantioselective form of these reactions used to synthesize L-DOPA by Knowles. Using a BINAP-ruthenium catalyst in these reactions was pioneered by Noyori. Palladium is a common catalyst for these reactions, (-5[1])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])
