Pd(dba)2 vs Pd2(dba)3: an in-depth comparison of …
With the help of mixed ligand catalytic systems, the analogous mechanisms behind the cognate performance by Pd(dba)2 and Pd2(dba)3 in catalyzing C-N and C-S coupling reactions were demonstrated. This information is instrumental in organic synthesis requiring Pd-catalyzed cross-coupling reactions and may also be valuable to other Pd-catalyzed transformations.
