2023年9月1日 · Using sodium sulfites and 2-mercaptobenzo heterocyclic compounds as starting materials, the unsymmetrical sulfur–sulfur bonds could be quickly constructed in the PPh 3 /I 2 reaction system under transition–metal-free conditions.

2013年9月9日 · An efficient and stereoselective spiroannulation of unsaturated enols is reported. Unsaturated β-dicarbonyl compounds undergo cyclization by reaction with catalytic I2–PPh3, affording the corresponding spiro enol ether derivatives, with complete regio- and stereoselectivity, under mild conditions. Utilizing

2018年5月17日 · An efficient one pot method for the synthesis of α -alkoxymethylphosphonium iodides is developed by using PPh 3 /I 2 combination at room temperature. Reaction conditions are found general to synthesize wide range of structurally variant alkoxymethylphosphonium iodides in high yield (70–91%).

2019年3月1日 · During the course of our studies, we found PPh 3 /I 2 /HCOOH could release CO efficiently and rapidly (Scheme 1). This result inspired us that PPh 3 /I 2 /HCOOH might be as CO precursor used in organic synthesis.

2023年10月30日 · An I 2 /PPh 3 -mediated synthesis of 3-thiolated chromones starting from 2-hydroxyphenylenones and sodium sulfinates was reported. This method features one pot manner, metal-free, easy performance, readily available starting materials and illustrating potential value for some biologically or pharmaceutically active compounds.

2024年5月21日 · We report a mild, operationally simple, convenient, and rapid method of peptide bond formation using triphenylphosphine and iodine. The developed protocol was utilized to couple coded, non‐coded, and challenging amino acids in 64–92 % yield.

2024年4月24日 · We report a mild, operationally simple, convenient, and rapid method of peptide bond formation using triphenylphosphine and iodine. The developed protocol was utilized to couple coded, non-coded, and challenging amino acids in 64–92% yield.
