CsF–Celite as an efficient heterogeneous catalyst for sulfonylation and desulfonylation of heteroatoms

CsF–Celite is found to be as an efficient reusable catalyst for sulfonylation and desulfonylation of heteroatoms. Sulfonamides and N-acylsulfonamides deprotect efficiently in the presence of CsF–Celite under solvent free conditions to give the free amines or amides in good to excellent yields.
