摘要

Summary The low solubility of tetramethyl titanate has so far prevented the laboratory use of titanate-catalyzed transesterifications with formation of methyl esters. Two procedures are described here, which allow the application of this exceedingly mild method to the synthesis of methyl esters: one uses methyl propionate/Ti (OEt) 4, the other one uses methanol/Gly-Ti, a new type of catalyst, prepared from Ti (OEt),/ethylene glycol 2: 1.
