A combination of Pd/C and H2 is found to dehydrogenate a wide range of substituted cyclohexanones and 2-cyclohexenones to their corresponding phenols with high isolated yields, with H2 as the only byproduct.
Sulfonyl Chlorides as Thiol Surrogates for Carbon–Sulfur Bond Formation: One-Pot Synthesis of Thioethers and Thioesters

A method to synthesize thioethers and thioesters directly from readily available sulfonyl chlorides is reported. We demonstrate that a transient intermediate formed during phosphine-mediated deoxygenation of sulfonyl chlorides can be trapped in situ by activated alcohols or carboxylic acids to effect carbon–sulfurbond formation. The method is operationally simple and tolerates a broad range of functional
Thionium ion promoted Michael acceptor: a sequence of Pummerer/Michael reactions for the stereoselective synthesis of 5-(1-(arylthio)vinyl)-oxazolines
