The effects of the reaction conditions on the metalation of phenyl p- Toluenesulfonate (Phenyl Tosylate)

Directed ortho metalation of phenyl p-toluenesulfonate (phenyl tosylate) was carried out and the reaction was found to be controlled by the conditions (base, solvent, temperature, with or without ligand) to some extent.

CATALYTIC SULFONYLATION OF PHENOL BY STERICALLY HINDERED SULFONYL CHLORIDES

The sulfonylation of phenol by substituted arenesulfonyl chlorides XArSO2Cl in the presence of triethylamine in benzene was studied by potentiometric titration.A linear relation was obtained between the logaritmhs of the catalytic rate constants and the steric constants Eso of the substituents in the sulfonyl chloride.The contribution from the induction and steric effects of the substituents at position2 to the kinetics of the process was assessed.It was concluded that the steric effect plays a predominant role over the induction and resonance effects.
