A di-phosphine chelating agent bearing anisyl, phenyl, and ethylene substituents acts as a ligand in the first industrial scale example of the asymmetric version of this reaction.
When this type of reaction is applied to coal liquefaction, tetralin is commonly used as the donor solvent - that is the transfer type of this reaction. A rhodium atom complexed to a cyclo-hexa-diene ring and two tri-phenyl-phosphine (try-FEN-ill-FOS-feen) groups acts as a high-turnover catalyst in this type of reaction. A di-phosphine chelating agent bearing anisyl, phenyl, and ethylene substituents acts as a ligand in the first industrial scale example of the asymmetric version of this reaction. A rhodium containing catalyst named for (*) Crabtree has a higher turnover rate than a similar catalyst named for Wilkinson when performing this reaction. DIBAL-H and LAH are commonly used for performing this type of reaction on carbonyls, and a solution of sodium in liquid ammonia reacts in this way with alkynes to give trans-substituted products. For 10 points, name this class of reactions which adds a light diatomic molecule across a double bond.
