CXLV.—Non-aromatic diazonium salts. Part IV. Thiazole-2-diazonium salts

Functionalized alkoxy arene diazonium salts from paracetamol.

Arene diazonium tetrafluoroborates can be synthesized from aromatic acetamides via a sequence of deacetylation, diazotation and precipitation, induced by anion exchange. The reaction is conducted as a convenient one-flask transformation with consecutive addition of the appropriate reagents. Exchange of solvents or removal of byproducts prior to isolation of the product is not required. The aren...

Photocatalytic Arylation of Alkenes, Alkynes and Enones with Diazonium Salts

Carbon–carbon bond formation by sp–sp or sp–sp crosscoupling is a key transformation in organic synthesis. Many methods, typically involving transition metal catalysis, are known, and the recent recognition of Richard F. Heck, Ei-ichi Negishi and Akira Suzuki by the Royal Swedish Academy of Sciences (Stockholm, Sweden) when they were awarded the Nobel Prize in Chemistry (2010) underlines the im...

Covalent electron transfer chemistry of graphene with diazonium salts.

Graphene is an atomically thin, two-dimensional allotrope of carbon with exceptionally high carrier mobilities, thermal conductivity, and mechanical strength. From a chemist's perspective, graphene can be regarded as a large polycyclic aromatic molecule and as a surface without a bulk contribution. Consequently, chemistries typically performed on organic molecules and surfaces have been used as...
