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.

Claim (Index 1):
A solid-supported catalyst, comprising:\n a catalytic metal in the form of a Pd +2  species having the formula PdZ 2 , wherein Z is selected from the group consisting of \u2014Cl, \u2014I, \u2014Br, \u2014OAc, and \u2014OTf, 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 R 1 , R 2 , R 3  and R 4  are independently \u2014H, an optionally substituted alkyl, an optionally substituted cycloalkyl, or an optionally substituted aryl; each R 5  and R 6  is independently \u2014H, an optionally substituted alkyl, an optionally substituted cycloalkyl, or an optionally substituted aryl; X is O, NH, or S; and wherein SS is a solid resin bead with the proviso that the solid resin bead is not silica.
