일반 설명

1,4-Diphenylbutadiyne reacts with [WI2(CO)3(NCMe)2] in CH2Cl2 to give the iodo-bridged dimer [W(μ-I)I(CO)(NCMe)(η2PhC2C2Ph)]2. 1,4-Diphenylbutadiyne on UV irradiation with olefins such as 2,3-dimethyl-2-butene, 1,4-cyclohexadiene and dimethyl fumarate yields cross-cycloaddition products.

애플리케이션

1,4-Diphenylbutadiyne was used in the preparation of 7,8-dehydropurpurin dimers via two-fold Pd-catalyzed [3+2] annulation of meso-bromoporphyrin.

Calciate-mediated intermolecular hydroamination of diphenylbutadiyne with N-phenyl and N-isopropyl-substituted anilines yields E- and Z-isomers of the corresponding 1-anilino-1,4-diphenylbut-1-ene-3-yne. In the case of HNPh(2) solely heterobimetallic K(2)Ca(NPh(2))(4) is able to effectively catalyze this hydroamination reaction in tetrahydrofuran at elevated temperatures.

7,8-Dehydropurpurin has attracted much attention owing to the dual 18π- and 20π-electron circuits in its macrocyclic conjugation. The two-fold Pd-catalyzed [3+2] annulation of meso-bromoporphyrin with 1,4-diphenylbutadiyne furnished 7,8-dehydropurpurin dimers. The 8(a) ,8(a) -linked dimer displays a red-shifted and enhanced absorption
