Copper (I) 1,3-R2-3,4,5,6-tetrahydropyrimidin-2-ylidenes (R=mesityl, 2-propyl): synthesis, X-ray structures, immobilization and catalytic activity

Novel Cu (I) N-heterocylic carbene complexes have been synthesized from CuX (X=Cl, Br) and 1,3-R2-3,4,5,6-tetrahydropyrimidin-2-ylidenes (R=2-Pr, mesityl). These were used in CO hydrosilylation and CO hydrocyanation reactions as well as in the ATRP of methyl methacrylate.
