L.Attorney, Agent or FirmInternational ClassesC07C 29/04 (20060101)C07C 29/00 (20060101) AbstractA catalytic composition useful for producing amides and primary alcohols from nitriles and alkenes respectively, comprising in the first instance water, a suitable nucleophile, and MHCl[P(R)3 ]2 wherein M is platinum, palladium, or nickel, and R is CH3, CH3 CH2, or i-Pr and in the second instance comprising the same reagents but limited to R being CH3. The addition of a phase-transfer catalyst facilitates both reactions where the aqueous solubility of the nitriles or alkenes is limiting in the reaction.Other References
