• Kinetics and mechanism of the formation of mono- and di-phthalate esters catalysed by titanium and tin alkoxides
  作者：Nicholas J. Hinde、C. Dennis Hall

  DOI：10.1039/a708468d

  日期：——

  The kinetics and mechanism of the formation of phthalate mono-esters and phthalate di-esters from phthalic anhydride and a variety of mono- and di-hydric alcohols are reported and discussed. The kinetic work is extended to a mechanistic study of the same reactions using titanium tetra-n-butoxide and tri-n-butyltin ethoxide as catalysts. The results support a mechanism involving alkoxy ligand exchange at the metal as a crucial step in the catalysis.
