The [n]cycloparaphenylenes ([n]CPPs)-n para-linked phenylenes that form a closed-loop-have attracted substantial attention due to their unique cyclic structure and highly effective para-conjugation leading to a myriad of fascinating electronic and op

Herein, we report a new method for synthesis of extended perylenes and terrylenes. The technique is based on the cascade dehydrative π-extensions (DPEX) of aryl aldehydes, in which stepwise annulations activate previously "dormant" substituents. Two

A novel catalyst‐free approach to benzoannulated oxygen‐containing heterocycles from fluorinated oligophenylenes is reported. Unlike existing methods, the presented reaction does not require an oxygen‐containing precursor and relies on an exter

Caryl–F bond activation has become an important and quickly developing method for construction of carbon-based materials. We report that alumina-mediated C–F bond activation (AmCFA) enables construction of PAHs with zigzag periphery. This method

The synthesis of ten ortho-fused PAHs bearing boronic pinacol ester groups (BPin) is reported. The products are obtained via modification of Mallory photocyclization in 45–99% yields. Among them are examples of highly strained molecules such as [4]

An unprecedented [6]helicene's cavity closure indicating the possibility of introducing seven-membered rings via alumina-mediated C–F activation is shown. This finding, in combination with a directed quadruple annulation of fluorinated oligoarylene

We have discovered a dual (i. e., soft and hard) Lewis acidity of alumina that enables rapid one-pot π-extension through the activation of terminal alkynes followed by C-F activation. The tandem reaction introduces an acenaphthene fragment - an esse

Pre-treated γ-alumina features reactive centers mimicking electronic interactions of propargyls with transition-metal-based catalysts. The combination of soft π-Lewis acidity and Brønsted basicity allows C-H propargyl activation under mild conditi
