Open air palladium catalyzed cyanation—the use of PMHS to protect from oxygen
Tetrahedron Letters(2007)
摘要
PMHS (polymethylhydrosiloxane) used in catalytic amounts has a remarkable ability to prevent catalyst poisoning by oxygen contamination during palladium catalyzed cyanation reactions. The procedure is applicable to a wide range of substrates and is so effective that it allows the reactions to be run fully open to the atmosphere.
