Abstract
A solid-supported catalyst ligand which chelates palladium (II) species to form a complex that functions as a heterogeneous catalyst that is stable and can be recycled without significantly losing any catalytic activity in a variety of chemical transformations, a method for producing the solid-supported catalyst ligand and a method for catalyzing a palladium cross-coupling reaction, such as the Suzuki-Miyaura, Mizoroki-Heck, and Sonagashira reactions.
Claims6
A solid-supported catalyst, comprising:
- a catalytic metal in the form of a Pd+2 species having the formula PdZ2, wherein Z is selected from the group consisting of —Cl, —I, —Br, —OAc, and —OTf, and
- a solid-supported ligand of formula (I)
- wherein the nitrogen atoms of the two oxazoline heterocycles of the solid-supported ligand chelate the catalytic metal;
- and
- wherein SS is a solid resin bead with the proviso that the solid resin bead is not silica.
