Opis

General description

Trichloroacetyl isocyanate (TAI) is a versatile building block in organic synthesis. It is also used as an in situ derivatizing reagent for the characterization of phenols, alcohols, and amines.

Application

• One-pot synthesis of 2-acylaminobenzimidazoles: A study on the synthesis of 2-acylaminobenzimidazoles via a reaction between trichloroacetyl isocyanate and 1,2-phenylenediamine derivatives (Shajari et al., 2018).


• Cabamothioate compounds: Research on the synthesis of S-aryl (trichloroacetyl) carbamothioate from a reaction of 2-naphthalenethiol or thiophenol derivatives and trichloroacetyl isocyanate (Shajari et al., 2021).


• Chiral calyx[4]arenes: Diastereoselective synthesis of inherently chiral calyx[4]arenes via reaction of trichloroacetyl isocyanate with 1,3-dihydroxy calixarene (Boyko et al., 2016).

Other Notes

Derivatizing reagent for the structural assignment to hydroxy compounds by NMR; Used in negative ion chemical ionization mass spectrometry
