摘要
A new tetraphosphine, the cis-cis-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane (Tedicyp) has been synthesized and used in palladium-catalyzed reactions. This tetraphosphine in combination with [Pd(C3H5)Cl](2) affords a very efficient catalyst for coupling reactions. Turnover numbers of 980 000 for allylic amination. 9 800 000 for allylic alkylation and 97 000 000 for Suzuki cross-coupling can be obtained in the presence of this catalyst.
