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