    • Our control experiment with Pd nanoparticles prepared in 1-buty1-2,3-dimethylimidazolium bis(trifluoromethanesulfonyl)imide (BDI-TFSI) not forming the carbene provided the biaryl 3a in 45% GC yield (vs. Entry 11 in Table 1). Apparently, the ligand-free Pd(0) itself has catalytic activity, although the possibility of participation of a Pd-carbene complex could not be completely excluded.
