Raney Nickel catalyzed hydrogenation of unsaturated carboxylic acids with sodium borohydride in water
Synthetic Communications, 2012Co-Authors: Gopal Krishna Rao, Narendra B. Gowda, Ramesha A. RamakrishnaAbstract:Abstract A mild, selective, and green method for the reduction of unsaturated carboxylic acids with sodium borohydride–Raney Nickel (W6) system in water is reported. This method is practical and safe and avoids use of organic solvents.

a chemoselective deoxygenation of n oxides by sodium borohydride Raney Nickel in water
Tetrahedron Letters, 2010Co-Authors: Narendra B. Gowda, Gopal Krishna Rao, Ramesha A. RamakrishnaAbstract:Abstract A simple and convenient protocol for deoxygenation of aliphatic and aromatic N -oxides to the corresponding amines in good to excellent yield using sodium borohydride–Raney Nickel in water is reported. Other functional moieties such as alkenes, halides, ethers, and amides are unaffected under the present reaction condition.

Ultrasound assisted cleavage of hydrazines by Raney Nickel
Synlett, 1991Co-Authors: Alexandre Alexakis, Nathalie Lensen, Pierre MangeneyAbstract:The reductive N-N cleavage of N-substituted N',N'-dimethylhydrazines to give primary amines by Raney Nickel/hydrogen is conveniently performed under atmospheric pressure of hydrogen by sonication of the reaction vessel in a simple ultrasound cleaner. Sterically hindered hydrazines are also cleaved and no racemization or debenzylation is observed.
