Solid-supported palladium(II) complex for catalyzing Mizoroki-Heck coupling reactions and a method thereof

A solid-supported ligand, comprising a reaction product of:

• a ligand of formula (I)
• or a salt, solvate, or stereoisomer thereof;
• and
• a solid support comprising silica;
• wherein the solid support is functionalized to comprise a substituted benzyl;
• a X atom in the compound of formula (I) is bonded to a carbon atom of the solid support;
• R1, R2, R3, and R4 are independently H, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted cycloalkylalkyl, an optionally substituted arylalkyl, an optionally substituted heteroaryl, an optionally substituted aryl, an optionally substituted heterocyclyl, an optionally substituted alkylthio, an optionally substituted alkanoyl, an optionally substituted aroyl, an optionally substituted heteroarylcarbonyl, an optionally substituted hydrocarbyl, an optionally substituted arylolefin, an optionally substituted arylalkylcarboxylic acid, or an optionally substituted vinyl;
• each R5 and R6 is independently H, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted cycloalkylalkyl, an optionally substituted arylalkyl, an optionally substituted heteroaryl, an optionally substituted aryl, an optionally substituted heterocyclyl, an optionally substituted alkylthio, an optionally substituted alkanoyl, an optionally substituted aroyl, an optionally substituted heteroarylcarbonyl, an optionally substituted hydrocarbyl, an optionally substituted arylolefin, an optionally substituted arylalkylcarboxylic acid, or an optionally substituted vinyl;
• and
• n is 1 with the proviso that X is O or S;
• or
• n is 2 with the proviso that X is N.
