Palladium Porphyrin Catalyzed Hydrogenation of Alkynes: Stereoselective Synthesis of cis-Alkenes
摘要:
(Tetraphenylporphyrin)palladium was developed as a catalyst for the chemoselective and stereoselective hydrogenation of alkynes to cis-alkenes by the syn-addition of hydrogen. Alkynes containing various functional groups were tolerated in the reaction, which gave the corresponding cis-alkenes in good to excellent yields.
