, p. 5916 - 5919 (2017)
An efficient protocol for the copper-catalyzed preparation of aryl dithiocarbamates from aryl iodides and inexpensive, environmentally benign tetraalkylthiuram disulfides was developed. The features of mild reaction conditions, high yields, and broad substrate scope render this new approach synthetically attractive for the preparation of potentially biologically active compounds.

A new, efficient copper-catalyzed C(sp 2)-S formation of phenyl dithiocarbamates starting from aryl iodides and tetramethylthiuram monosulfide (TMTM) was developed. The target compounds, phenyl dithiocarbamates with active sites, were synthesized smoothly in good to excellent yields. The easy performance, high yields, decent functional group compatibility, and cost-effective substrates make the protocol practical and attractive in C-S bond formation.

A convenient and useful protocol for the synthesis of diverse S-aryl dithiocarbamates was studied. Starting from arylboronic acid and tetraalkylthiuram disulfide, copper-catalyzed C–S coupling proceeds smoothly to give the desired S-aryl dithiocarbamates in good to excellent yields. The broad substrate scope, short reaction time, easy performance, cheap substrates, and nice yields make this approach attractive, showing its practical synthetic value for the preparation of some biologically or pharmaceutically active compounds.
A Highly Efficient CuCl 2 -Catalyzed C-S Coupling of Aryl Iodides with Tetraalkylthiuram Disulfides: Synthesis of Aryl Dithiocarbamates

A highly efficient copper(II)-catalyzed C-S cross-coupling reaction of aryl iodides with tetraalkylthiuram disulfides was developed. With only 1 mol% of CuCl 2 as catalyst, zinc powder as reductant, and K 2 CO 3 as base, aryl iodides reacted with tetraalkylthiuram disulfides in DMSO furnishing the corresponding aryl dithiocarbamates in good to excellent yields. This protocol is an improvement of previous work, it features convenient performance, low addition of catalyst, no requirement for any ligand, and provides good yields. The method has a broad substrate scope and uses cheap and readily available starting materials.
