资源简介：
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.
