We have established that a cationic rhodium(I)/H(8)-BINAP complex catalyzes the complete regioselective intermolecular 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，一种带正电荷的铑（I）/H（8）-BINAP 配合物可以催化芳基乙炔基醚与腈或异氰酸酯的完全区域选择性的交叉环三聚反应，在室温下得到 2,4-二芳基氧代吡啶或 4,6-二芳基氧基-2-吡啶酮。
