General procedure: To an oven-dried screwed 20 mL vial were added (NHC)CuCl (c7 or c8, 0.2 mmol) suspended in dry THF (3 mL); in another vial, [tBu3PN]Li (1b, 42.3 mg, 0.95 eq.) was also dissolved in dry THF (3 mL), then the vial was put into glove-box fridge (-35 C) for one hour. Then the cold mixture was dropped into the (NHC)CuCl/THF suspension slowly under stirring and the suspension was turned into clear solution as the lithium salt added.
