The direct S-cyclopropylation of thiophenols using tricyclopropylbismuth is reported. The reaction is catalyzed by copper(II) acetate and operates under mild conditions to afford the corresponding aryl cyclopropyl sulfides in moderate to good yields. This reaction represents the first use of an organobismuth reagent in C(sp3)–S bond formation.

The copper-promoted S-cyclopropylation of thiophenols using cyclopropylboronic acid is reported. The procedure operates under simple conditions to afford the corresponding aryl cyclopropyl sulfides in moderate to excellent yields. The reaction tolerates substitution in ortho-, meta- and para-substitution as well as electron-donating and electron-withdrawing groups. The S-cyclopropylation of a thiophenol was also accomplished using potassium cyclopropyl trifluoroborate.
Base-controlled Fe(Pc)-catalyzed aerobic oxidation of thiols for the synthesis of S-S and S-P(O) bonds

, p. 4236 - 4242 (2018/06/21)
Fe(Pc)-Catalyzed aerobic oxidation of thiols for the synthesis of disulfides has been developed under mild reaction conditions. In addition, an aerobic oxidative cross-dehydrogenative coupling (CDC) reaction of thiols with P(O)-H compounds (H-phosphonates and H-phosphine oxide) for the formation of S-P(O) bonds has been demonstrated under the Fe(Pc) catalysis system with a base additive. Control experiments revealed that the use of a base (DIPA) in this system controls the synthetic pathways in which thiophosphates are formed.

Oxidative chalcogenation reaction using molybdenum(V) reagents provides fast access to a wide range of nonsymmetric aryl sulfides and selenides. The established protocol is tolerated by a variety of labile functions, protecting groups, and aromatic heterocycles. In particular, when labile moieties are present, the use of molybdenum(V) reagents provides superior yields compared to other oxidants.

DCDMH-mediated phosphorylation of versatile thiols with H-phosphonates for the preparation of synthetically and biologically important thiophosphates was demonstrated. Without metal catalysts and other additives, phosphorylation occurred to give the desired products with good to excellent yields within 10 min at ambient temperature in the air.

We report an operationally simple, metal-free approach for the late-stage introduction of the important lipophilic hydrogen-bond donor motif, SCF2H. This reaction converts diaryl- and dialkyl-disulfides into the corresponding aryl/alkyl-SCF2H through the nucleophilic transfer of a difluoromethyl group with good functional group tolerance. This method is notable for its use of commercially available TMSCF2H, and does not rely on the need for handling of sensitive metal complexes.
Synthesis of β-Hydroxysulfides from Thiophenols and Disulfides with tert-Butyl Hydroperoxide as the Oxidant and Reactant

, p. 315 - 318 (2016/08/19)
In this Communication, we developed a new procedure for the synthesis of 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.

, p. 95753 - 95759 (2016/10/22)
Selective transformation of thiols to disulfides by means of oxidative dehydrogenation has been described using silica supported iron oxide under base- and solvent-free reaction conditions at room temperature in an open atmosphere. The easiness of catalyst preparation, green reaction conditions, easy separation of the formed products and catalyst from the reaction mixture, and recyclability of the catalyst, are the most attractive facets of our synthetic procedure which, being ecofriendly, will find immense applications in academic and industrial sectors.
