Solid-supported catalyst for cross-coupling

1:

• 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 R1, R2, R3 and R4 are independently —H, an optionally substituted alkyl, an optionally substituted cycloalkyl, or an optionally substituted aryl;
• each R5 and R6 is independently —H, 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.
