We have established that a cationic rhodium(I)/H8−BINAP complex catalyzes the complete regioselectiveintermolecular cross-cyclotrimerization of aryl ethynyl ethers and nitriles or isocyanates leading to 2,4-diaryloxypyridines or 4,6-diaryloxy-2-pyridones at room temperature.
我们已经确定,阳离子铑(I)/ H 8 -BINAP络合物催化芳基乙炔基醚和腈或异氰酸酯的完全区域选择性分子间交叉三聚,从而在2,4-二芳氧基吡啶或4,6-二芳氧基-2-吡啶酮室内温度。
