摘要： The invention relates to the field of chemistry, especially organic chemistry, and more specifically the field of heterogeneous palladium catalysts used to catalyse chemical reactions involving the formation of carbon-carbon bonds. The invention also relates to a method for synthesising a heterogeneous palladium catalyst that can catalyse a C—C coupling reaction, the method essentially including steps of providing a solid substrate onto which groups of formula —PR1R2, wherein R1 is an optionally substituted alkyl group, or an optionally substituted cycloalkyl group, et R2 is an optionally substituted aryl group or an optionally substituted heteroaryl group, have been covalently bonded, and incorporating a catalytically effective amount of palladium into the resulting substituted substrate. The invention further relates to the resulting catalysts and to the uses thereof in C—C coupling reactions.
