FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing diaryl acetylenes of general formula 
, where R=aryl; R1=aryl, by reacting an organotin compound with aryl iodides in the medium of an organic solvent, in the presence of a catalyst - a palladium (II) complex, characterised by that the organotin compound used is tin tetraalkynylides and the reaction takes place at temperature 60-100°C.
EFFECT: use of the present invention enables to obtain diaryl acetylenes using a simple and safe method.
