This review deals with the different accesses leading to the dibenzofuran nucleus in the last fifteen years.
A general and authoritative literature overview on Pd-catalyzed cross-dehydrogenative coupling reactions of (hetero)arenes from the origins to 2023, where not only the synthetic aspects were described but also the most relevant mechanistic features.
This review shows that biomarkers could be used to establish the sedimentary depositional environments, redox conditions, and organic matter enrichments of shales that are critical to the deep energy exploitation.
Emerging metal-catalysed intramolecular X–CH activation strategies enable efficient, step-economical access to π-conjugated heteroaromatics for next-generation organic materials.
Dibenzofurans featuring a 2,2′-biazulene framework were prepared in good yields by Brønsted acid-promoted annulation of 2,3-di(1-azulenyl)benzofurans in 100% H3PO4.
