Using phenyliodine diacetate as an oxidant and nickel acetate as a promoter, a wide range of unsymmetric thiosulfonates could be furnished easily in moderate to excellent yields starting from N-substituted O-thiocarbamates and sodium sulfinates. This protocol features mild conditions, short reaction times, and high atomic utilization, which can provide an alternative method for the synthesis of unsymmetric thiosulfonates. In addition, the reaction could be scaled up on a gram scale, showing potential application value in industry.

An odourless and efficient protocol for the synthesis of benzyl phenyl sulfides was reported. Starting from environmentally friendly phenyldithiocarbamates and commercially available benzyl halides as starting materials, the target compounds (benzyl phenyl sulfides) could be obtained smoothly and easily by using copper salt as catalyst and Cs2CO3 as base. This method features ligand/additive free, the use of readily available starting materials, inexpensive catalysts, and good substrate suitability, illustrating its potential synthetic value for the convenient preparation of some biologically active molecules.

A highly efficient and convenient method for the waterinvolved synthesis of β-keto dithiocarbamates has been developed. In the presence of minimal water, the desired products were obtained in good to excellent yields by using thiuram disulfide reagents and substituted α-haloacetophe-nones as starting materials. This protocol features high atom economy, mild conditions, good functional tolerance and good to excellent yields, showing potential value for the preparation of some biologically and pharmaceutically active compounds.

In the presence of iodine, the synthesis of S‐benzoazolyl chromone derivatives by one‐pot manner is reported. Thus, 2‐aminophenol firstly reacted with tetramethylthiuram disulfide (TMTD) to form 2‐mercaptobenzoxazole, and then coupled with 2‐hydroxyphenyl enaminones to obtain S‐benzoazolyl chromones through one‐pot manner. This method features mild conditions, easy operation, environmentally friendliness and wide substrate scopes, illustrating practical application value in organic synthesis.

Under transition‐metal‐free conditions, a series of unsymmetrical disulfides could be quickly and conveniently obtained by NIS (N‐Iodosuccinimide)‐promotion in one pot manner. This method features mild conditions, easy operation, short reaction time and wide substrate scopes. It's noteworthy that the desired products could be obtained in moderate to good yields from inexpensive and easily available starting materials, providing an alternative way to afford various unsymmetrical disulfides.
