The trifunctional triptycene monomers are synthetically more accessible and compatible with more bridging methods, which makes them appealing building blocks for the construction of dispersible COF materials with weaker interlayer interactions. WebDec 31, 2024 · Nevertheless, a π-extended chiral triptycene with all three aromatic rings being different was obtained (87% ee). To explain differences in the behavior of precursors, the authors investigated mechanistic aspects of the carbocation-involving oxidative dehydrogenation. It was determined that high strain causes an undesired carbocation ... happy hour grand ave
