Among the bisphosphine ligands, we have previously developed C n-TunePhos (n = 1-6) as a family of ligands with tunable bite angles. The increase in spacer -CH2- groups in this family of ligands causes changes in ligand dihedral angl
Selective α-Cleavage Cycloaddition of Oxiranes with Heterocumulenes Catalyzed by Tetraphenylstibonium Iodide

A catalytic amount of tetraphenylstibonium iodide (1) promoted unusual cycloadditions of oxiranes with isocyanates or carbodiimides, forming 3,4-disubstituted oxazolidin-2-ones 2 and oxazolidin-2-imines 4 under very mild conditions, respectively.In partic
