Phosphorus-containing dendrimers and their transition metal complexes as efficient recoverable multicenter homogeneous catalysts in organic synthesis

Metalladendrimers of generation 3 with either 24 terminal palladium or ruthenium diphosphine complexes or one ruthenium diphosphine complex located at the core have been found to be efficient, recoverable catalysts in three general organic reactions: Stille couplings, Knoevenagel condensations, and Michael additions.
