Application

1,1,1-Tris(hydroxymethyl)ethane can be used as a reactant to synthesize:
  • Hyperbranched polyesters by polycondensation reaction with dimethyl esters of aliphatic dicarboxylic acids.
  • Trimeric anionic surfactants by reacting with long-chain α-bromo fatty acids.

It can also be used as a tridentate O-donor ligand in the:
  • Copper-catalyzed cross-coupling reactions between aryl iodides and amides, thiols, and phenols to prepare corresponding products via formation of C−N, C−S, and C−O bonds.
  • N-arylation of azaheterocycles with aryl iodides using copper-catalyst.
