FIELD: chemistry; technological processes.
SUBSTANCE: invention relates to methods of producing silicone acetylene compounds containing four Si-Csp bonds in a molecule. Disclosed is a method of producing tetraalkynylsilanes by reacting silicon tetrachloride with 1-alkynes in 1,2-dichloroethane medium in presence of 120 mol% zinc triflate and 120 mol% of diisopropylethylamine at 45 °C for 4–6 hours.
EFFECT: simple and efficient method of producing tetraalkynylsilanes using commercially available compounds which enables to involve 1-alkynes with different substitutes.
