The Synthesis of Phenyl Carboxylates from p-Bromophenol and Carboxylic Acid

The reaction of p-bromophenol with carboxylic acids in the presence of triphenylphosphine and triethylamine proceeded at a high temperature, with the elimination of hydrogen bromide, to give phenyl carboxylates and small amounts of p-bromophenyl carboxylates.

Preyssler catalyst: An efficient catalyst for esterification of cinnamic acids with phenols and imidoalcohols

In the present work a series of eco-friendly Preyssler solid acids and their salts H14[NaP5W29MoO110] (PW), H14[NaP5W30O110] (PWMo), K12.5Na1.5[NaP5W30O110]·15H2O (PWK), K12.5Na1.5[NaP5W29MoO110]·15H2O (PWMoK) and 10% silica-supported H14[NaP5W29MoO110] (PWSiO2), and H14[NaP5W30O110] (PWMoSiO2) have been used as catalysts for the direct esterification of cinnamic acids with phenols or 2-(N-phthalimidoethanol). Effects of the reaction conditions were studied, including temperature, reaction time, and type and amount of catalyst. These solids were characterized by several techniques, such as diffuse reflectance spectroscopy, Fourier transformed infrared spectroscopy, optical and scanning electron microcopies, and X-ray diffraction, among others. The most adequate catalyst for performing the title reaction was H14[NaP5W30O110] (PWMo). The catalyst was applied for the synthesis of various substituted cinnamates, giving very good yields.
