Electrophilic perfluoroalkylating agents

Article Abstract:

The synthesis of perfluoroalkylating reagents like the (perfluoroalkyl)- phenyliodonium triflates (FITS) follows electrophilic methods. FITS undergo perfluoroalkylation reaction with nucleophiles and unsaturated compounds. FITS reagents carry out reactions on a polymer support to overcome the problem of product isolation from the reaction mixture. The perfluoroalkyl chalcogen salts give C-perfluoroalkylation while FITS gives both C- and O-perfluoroalkylation.

Electrophilic NF fluorinating agents

Article Abstract:

A strong electrosensitive character of fluorine explains the electrophilic fluorinating behavior of NF compounds, like hypofluorites. NF-class reagents selectively position the fluorine atom at the chosen carbanionic sites in the molecule. The use of R2N- and R3N+-carriers stabilizes these reagents during storage. Aromatic compounds undergo fluorine substitution reactions with NF compounds. Carbanions are highly reactive towards the NF-fluorinating reagents.

The electrophilic nature of carbenoids, nitrenoids, and oxenoids

Article Abstract:

Research suggests that the "anions" such as carbenoids, nitrenoids, and oxenoids share common chemical properties like electrophilic nature, reactions with nucleophiles, and organometallic compounds. Data indicate that a metal and a group leaving the chemical reaction simultaneously bond to form a C, N, or O atom, which give rise to unique properties of these anions.
