An oxidative β‐Csp3−H functionalization of tert‐butanol (tBuOH) for the construction of C−S bonds through an iodine‐catalyzed Csp3−H/S−H coupling was successfully achieved. Different kinds of mercaptans were shown to be good coupling partners, affording the desired products in good yields. This protocol not only offers a novel method for the synthesis of β‐hydroxy thioethers, but also provides an effective

An efficient and rapid procedure for ring opening reaction of various epoxides with phenol and thiophenol derivatives was developed. The procedure can be obtained at room temperature under solvent-free condition in presence of (C4H12N2)(2)[Bicl(6)]Cl center dot H2O (1 mol %). This catalyst can be reused several times without significant loss of activity. (C) 2013 Elsevier Ltd. All rights reserved.

β‐hydroxysulfides from thiophenols or diaryl disulfides with TBHP as the oxidant. In the presence of zinc iodide or potassium iodide, with TBHP as the oxidant and pre‐reactant, thiophenols and diaryl disulfides reacted with the methyl group of tBuOH smoothly and selectivity to give the corresponding 2‐methyl‐1‐(arylthio)propan‐2‐ols as the terminal products in moderate to good yields.

A new mononuclear low-spin nickel(II) dithiolato complex, [NiL2] (1), reacts with copper iodide to form the hetero-octanuclear cluster [Ni(L)2}2(CuI)6] (2) with four trigonal-planar CuI2S and two tetrahedral CuI2S2 sites; anagostic interactions between the nickel(II) ions and aromatic protons have been demonstrated by variable-temperature NMR studies to pertain in solution.
