Sterically Crowded Sulfonate Esters: Novel Leaving Groups with Hindered S-O Cleavage

Article abstract of DOI:10.1055/s-1987-28045

Reagents and procedures for the preparation of tert-butyl sulfonate esters 2 and 2,2,2-trifluoro-1,1-diphenylethane sulfonate esters 3 (TDE-sulfonates) are described.In these new sulfonates, S-O-scission is reduced significantly by steric hindrance.
