The NaB H,-PdCI,-polyethylene glycol-CH,CI, system has been found to be effective for the hydrogenation of acetylenic triple bonds to the corresponding cis-alkenes. ... The properties of polyethylene glycol (PEG) make it an excellent substitute for crown ethers in many reactions, and its use as a co-solvent has been reported.l*, We have now found that selective hydrogenation of acetylenic triple bonds takes place with NaBH,-PdCI, in PEG-CH,Cl, system^,^*^ providing the first ...
