Application In Synthesis of m-Methoxyphenol The article mentions the following:
In this sense, the use of propylsulfonic acid supported in FDU-5 (FDU-5-Pr-SO3H) as a catalyst for the synthesis of coumarins I (R1 = 7-OH, 5-Me-7-OH, 7,8-OH2, 7-OMe; R2 = Me, Ph) and 4-methyl-2H-benzo[h]chromen-2-one via Pechmann condensation in solvent-free medium was investigated. FDU-5-Pr-SO3H was synthesized by co-condensation of MPTES and TEOS. FDU-5-Pr-SO3H was used as catalyst for the synthesis of 7-hydroxy-4-methylcoumarin and their reaction conditions were optimized. The optimization process involved the study of the influence of the catalyst load, Resorcinol:EAA molar ratio, reaction temperature and reaction time. The optimal conditions were: catalyst load of 1.65 mol%, reactants molar ratio of 1:1.5, temperature 130°C and 60 min of reaction time. Under these conditions, the FDU-5-Pr-SO3H material showed excellent yield (96.5%) and turn over frequency (59 h-1). Finally, the synthesized material was assessed as a catalyst with other phenolic compounds and Et acetoacetate and with Et benzoylacetate. The obtained products were isolated and identified by comparison of their spectral data with those reported in literature; from these results, it can be concluded that the catalyst is active with a wide range of phenolic substrates. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6Application In Synthesis of m-Methoxyphenol)
m-Methoxyphenol(cas: 150-19-6) may be used in synthesis of:C(4) symmetric calix[4]resorcinarene, 2-nitroso-5-methoxyphenol, 6-methoxy-2(3H)-benzoxazoloneApplication In Synthesis of m-Methoxyphenol
