A mild and practical method for the transition metal-free protodecarboxylation of aromatic acids using readily available and safe sodium persulfate as initiator was described. This environment-friendly decarboxylation approach was performed at 60 °C in ethanol and could easily scale up to the gram level with a good yield. In Particular, the tandem reactions of decarboxylation and halogenation were achieved by the addition of the corresponding halogenating reagents to the reaction system.

A zinc-catalyzed Williamson ether synthesis is described with microwave heating in the presence of DMF or stirring in an oil-bath using THF as solvent and in the absence of base. Zinc powder was found to be a highly efficient catalyst for the synthesis of aromatic ethers using microwave heating in the presence of N,N-dimethylformamide as well as under stirring in an oil-bath using tetrahydrofuran as solvent without any inorganic base. This method can be used for selective mono-, di- or tri-O-alkylations.

The alkylation of phloroglucinol dialkyl ethers with alcohols or alkyl halides leads, depending on the reaction conditions, either to products of O- or C- alkylation, or to C,O-alkylation products.Reaction conditions were found which enable us to obtain pure phloroglucinol trialkyl ethers.A convenient preparative method for the synthesis of phloroglucinol trialkyl ethers consists in the alkylation of phloroglucinol dialkyl ethers in a two-phase system in presence of phase-transfer catalysts.
