In the presence of triphenylphosphine as a mild reductant, the use of catalytic amounts of Mo(CO)6 and an ortho-quinone ligand enables the intermolecular reductive coupling of aromatic aldehydes and the intramolecular coupling of aromatic ketones to produce functionalized alkenes. Diaryl- and diheteroaryl alkenes are synthesized with high (E)-selectivity and a tolerance toward bromide, iodide, and steric
在三苯膦作为温和还原剂存在的情况下,使用催化量的 Mo(CO) 6和邻醌配体能够实现芳香醛的分子间还原偶联和芳香酮的分子内偶联以产生官能化烯烃。二芳基和二杂芳基烯烃的合成具有高 ( E ) 选择性和对溴化物、碘化物和空间位阻的耐受性。在类似条件下二羰基化合物的分子内偶联得到单取代和双取代的菲。
