Microwave-Assisted Copper-Catalyzed Cross-Coupling Reaction of Thiols with Aryl Iodides in Water
Chen, Yi-An,Badsara, Satpal Singh,Tsai, Wan-Ting,Lee, Chin-Fa
, p. 181 - 186 (2015)
Microwave-promoted C-S bond formation from thiols and aryl iodides in the presence of a copper catalyst is reported. A combination of copper(II) oxide and 1,10-phenanthroline catalyzes this reaction. A variety of aryl iodides react smoothly with thiols to provide the corresponding aryl sulfides in good to excellent yields. Notably, the reactions proceed in water with a short reaction time (30 minutes). This system shows broad functional-group tolerance; amino, chloro, bromo, acetyl, and nitro groups are unaffected by the reaction conditions.

The asymmetric Michael addition of malonates to α,β-unsaturated aldehydes using a modified Jorgensen-Hayashi organocatalyst in EtOH:brine solvent media is reported. The procedure proceeds smoothly to afford the corresponding Michael adducts in good yields with excellent enantioselectivities. The resulting Michael adducts represent excellent building blocks for the synthesis of chiral indoles. The asymmetric Michael reaction using a modified Jorgensen-Hayashi organocatalyst in EtOH:brine solvent media is reported. This procedure afforded the corresponding Michael adducts in good yields and with excellent enantioselectivities. The resulting adducts were further used as chiral building blocks for the synthesis of indoles. Copyright

The general procedure for the rhodium-catalyzed cross-coupling of thiols with aryl iodides is described. The catalytic system consists of 5 mol % of [RhCl(cod)]2 and 10 mol % of PPh3 as a ligand. A variety of aryl iodides reacted with thiols, giving aryl thioethers in good to excellent yields. It is important to note that the deactivated aryl iodides such as 4-iodoanisole is worked smoothly to provide the corresponding aryl thioethers in excellent yields. Functional groups such as free-amines, chloro, are all tolerated under the employed reaction conditions.
Recyclable heterogeneous supported copper-catalyzed coupling of thiols with aryl halides: base-controlled differential arylthiolation of bromoiodobenzenes

Alumina-supported copper sulfate efficiently catalyzes the 5-arylation of aromatic, heteroaromatic and aliphatic thiols with aryl as well as heteroaryl halides under aerobic, ligand-free conditions. This protocol provides an easy access to a variety of thioethers as well as unsymmetrical bis-thioethers by base-controlled differential coupling of thiols with iodo- and bromo-substituents in an aromatic halide. The catalyst is inexpensive, non-air sensitive, environmentally friendly and recyclable.

Control of aggregation behavior of derivatized surfactants by moderately polar functional groups as well as the role of charge-transfer interactions governing photophysical phenomena was studied using surfactants incorporating the diphenylacetylene (tolan
