The iodine compounds of the present invention corresponds to those of formula (I), wherein R1, R1' and X have several meanings. These iodine compounds gives rise to the amination of several substrates without the need of catalysts, especially metal catalysts, and confer to the amination reaction the further advantage of being performed under mild conditions, which is of interest for industrial-scale production of nitrogenated compounds with pharmaceutical, biological or medicinal applications. Therefore, the iodine compounds of the invention are useful as amination agents. The invention also discloses several processes for the preparation of the iodine compounds of formula (I).

A direct metal-free amination of arylalkynes has been developed, which proceeds by reaction of the terminal alkyne with the hypervalent iodine reagent PhI(OAc)NTs(2) within a single-step operation. This unprecedented intermolecular C-H to C-N bond conversion provides rapid access to the important class of ynamides. In addition to the title reaction, the related transformation between alkylated alkynes
