A phosphine-free heterogeneous coupling of acyl chlorides with terminal alkynes catalyzed by an MCM-41-immobilized palladium complex

Huang, Bin,Yin, Lin,Cai, Mingzhong

, p. 3137 - 3144 (2013)

The phosphine-free heterogeneous coupling of acyl chlorides with terminal alkynes was achieved in triethylamine at 50 °C in the presence of a 0.2 mol% 3-(2-aminoethylamino)propyl-functionalized MCM-41-immobilized palladium complex [MCM-41-2N-Pd(OAc)2
