(A)Write the mechanism of the following raction : CH3CH2OHHBr−−→CH3CH2Br+H2O (b) Write the equation involved in Reimer-Tiemann reaction. View Solution The electrophile involved in the Reimer-Tiemann rea
A Reimer-Tiemann reaction of 2,3-dichlorophenol with carbon tetrachloride gives 2,3-dichloro-4-hydroxy-benzoic acid, a novel intermediate, which is then reacted with thiophene in the presence of phosphorus pentoxide or polyphosphoric acid to give 2,3-dichloro-4-(2- thienoyl)-phenol. This ...
