173.Ru-Catalyzed Oxidations with Iodosylbenzene Derivatives. Substituent Effects on Selectivity in Oxidation of Sulfides and Alcohols
Mueller, Paul,Godoy, Jose
, p. 1790 - 1796 (1983)
Oxidation of sulfides witth PhIO/RuCl2(PPh3) leads to sulfones.Electronwithdrawing substituents in the aromatic ring of PhIO reduce the reactivity and improves selectivity of the system.Thus, with m-iodosylbenzoic acid sulfides are converted to sulfoxide.Under the same conditions aliphatic primary alcohols are transformed to aldehydes with m-iodosylbenzoic acid, while PhIO affords carboxylic acids.

In the presence of boron trifluoride, a variety of alkynyl sulfides and alkynyl sulfoxides undergo tandem cross-coupling/[3,3]-sulfonium rearrangement followed by 5-exo-dig heterocyclization. The strategy provides concise access to novel tetrasubstituted

The controlled metal-free synthesis of a vast variety of heteroatom-containing cyclobutene-triflones [bis(trifluoromethylsulfonyl)cyclobutenes] and cyclobutenones has been developed starting from heteroatom-substituted alkynes and a pyridinium salt (a latent Tf2C=CH2 source). This powerful methodology, involving cyclization reactions, allows for the selective preparation of oxygen-, nitrogen-, bromine-, chlorine-, iodine-, sulfur-, selenium-, tellurium-, phosphorus-, and silicon-functionalized cyclobutene derivatives. (Figure presented.).
