WebThe absence of IPr.HCl completely inhibited the reaction (entry 9), whereas the reaction still gave 3a in 14% yield without the addi-tion of PCy 3 (entry 13), demonstrating the vital role of IPr and the promoting effect of PCy 3. In fact, a yield of 68% was detected WebDec 14, 2014 · Open access Graphical abstract A novel route for the large-scale synthesis of [Au (NHC) (OH)] complexes is reported. Using this new methodology, several [Au (NHC) (OH)] complexes were readily and efficiently accessed on multi-gram scale (up to 20 g).
