Preparation and syntheticapplications of [2.2]paracyclophane trifluoroborates in the Suzuki–Miyaura cross‐coupling reaction is described. The trifluoroborates and halotrifluoroborates described herein are bench‐stable, crystalline solids accessible on multi‐gram scale and can be cross‐coupled with a wide range of aryl(hetero) halides.

The modular synthesis of Au(I)/Ru(II) decorated mono- and heterobimetallic complexes with π-conjugated [2.2]paracyclophane is described. [2.2]Paracyclophane serves as a rigid spacer which holds the metal centers in precise spatial orientations and allows metal-to-metal distance modulation. A broad set of architectural arrangements of pseudo -geminal, -ortho, -meta, and -para substitution patterns were
