p-Toluenesulfonic acid mediated hydroarylation of cinnamic acids with anisoles and phenols, under metal and solvent-free conditions

Hydroarylation of cinnamic acids with anisoles and phenols mediated by p-toluenesulfonic acid (p-TSA) under metal and solvent-free conditions gave 3-(4-methoxyphenyl)-3-phenylpropanoic acids and dihydrocoumarins, respectively, in high yields and excellent selectivity.
