Synthesis, structures and reactions of acylsulfenyl iodides with theoretical investigations.

ABSTRACT: A series of acylsulfenyl iodides (RCOSI) were synthesized by the reactions of carbothioic acid group 11-16 element derivatives with iodine or N-iodosuccinimides in moderate to good yields. The structure of the PhCOSI was nearly square planar based on the X-ray analysis, where the C[double bond, length as m-dash]O⋯I distance (3.153(5) Å) was significantly shorter than the sum of the van der Waals radii of the atoms (Σr _vdW), indicating close contact within the molecule. The distances between an iodine atom and the neighbouring two iodine atoms were also less than Σr _vdW, perhaps due to the energy lowering effect of the interactions. The acylsulfenyl iodides readily reacted with alkenes and alkynes to give the expected addition products in moderate
