This short review aims to give an overview to related properties of pyrylium salts, their historical significance, and summarize the recent progress in the field of deaminative transformations using these reagents. 1 Introduction. 2 Pyrylium and Pyridinium Salts. Historical Context. Structure and Reactivity. Pyrylium Synthesis. Princeton University Library One Washington Road Princeton, NJ USA () one-component synthesis of pyrylium salts through the use of a carbonyl group in lieu of a proximal arene moiety. According to our proposed mechanism, electrophilic at-tack at the â carbon of 2 results in a carbocation formation at the R carbon, thereby leading to ring closure of intermediate A via lone pair attack (Scheme 1). In this. A new synthesis method has been used to obtain a pyrylium salt that is trisubstituted with phenyl groups at positions 2,4, and 6. The phenyl group of the 4-position has a metacrylate group in the.
