  Photolability of Per-Arylated Butadienes: En Route to Dihydronaphthalenes

  摘要：

  Arylated butadienes were prepared employing transition-metal coupling techniques and characterized via UV/vis spectroscopy and X-ray crystal structure analysis. Identification of byproducts led to a photochemical route toward novel multiarylated dihydronaphthalenes. Arylbutadiene-dihydronaphthalene cyclization occurs in solution and in the solid state. Upon substitution of hexaphenylbutadiene, absorption is red-shifted and stability under ambient light is even more reduced.

  The intermolecular oxidative coupling of arylboronic acids with internal alkynes efficiently proceeds in a 2:2 manner in the presence of palladium acetate, a triaryl phosphite or phosphate, and silver carbonate as catalyst, ligand, and oxidant, respectively, to produce the corresponding 1,4-diaryl-1,3-butadiene derivatives.

  芳基硼酸与内部炔烃的分子间氧化偶联可在乙酸钯，亚磷酸三芳基酯或磷酸根以及分别作为催化剂，配体和氧化剂的碳酸银存在下以2：2方式有效进行，以产生相应的1， 4-二芳基-1,3-丁二烯衍生物。
