Hydrocarbon Molecules with Novel Structure: a Dehydroannulene with Silver(I)-Complexing Ability and a Double C60 Adduct of Pentacene (ORGANIC MATERIALS CHEMISTRY-High-Pressure Organic Chemistry)

Abstract

The first silver(I) complexes of tetradehydro[16]annulene fused with four bicyclo[2.2.2]octene units were synthesized, and the incorporation of the silver atom into the cavity center was shown by X-ray crystallography. The degree of complexation was affected by the counteranion. In contrast to the AgOTf complex, the AgSbF6 complex was found to be more strongly coordinated to the dehydroannulene ligand. On the other hand, the solid-state reaction using high-speed vibration milling technique was applied to cycloaddition of fullerene C60 to pentacene. There was obtained a new C60 double adduct as a unique product for the solid-state reaction.
