experimental part, p. 1477 - 1482 (2012/06/18)
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.

An enviro-economic route for tosylation of alcohols and selective monotosylation of diols in good yield directly using p-toluenesulfonic acid together with metal-exchanged montmorillonite instead of p-toluenesulfonyl chloride or p-toluenesulfonic anhydrid
2,2-Bis(ethylthio)ethanenitrile: preparation and use as a one or two carbon nucleophile
Bates, Gordon S.,Ramaswamy, S.
, p. 2006 - 2009 (2007/10/02)
2,2-Bis(ethylthio)ethanenitrile 1 was prepared in high yield from 2,2-bis(ethylthio)ethanal 2.Alkylation of the potassium salt of 1 with various alkylating agents and conjugate addition to cyclic α,β-unsaturated ketones provided high yields of the alkylation products of 1.The potential one and two carbon chain extension capability of this new reagent has been demonstrated.
