14.6.5 Thiopyrylium Salts (Update 2021)

Abstract

This is an update to the original Science of Synthesis chapter from 2003 (Section 14.6) on thiopyrylium salts. This update covers articles from the literature that were published between 2003 and 2020. Several methods for the synthesis of thiopyrylium salts that were covered in the previous chapter are also included in this update, because some new applications of thiopyrylium salts were explored in those works.

Key words

thiopyrylium salts - thioxanthylium - thiopyrylium - photocatalysts - ring enlargement - elimination - dehydrogenation
