METHOD OF OBTAINING 1,2,4-TRIPHENYLBENZOL

摘要

FIELD: chemistry. ^ SUBSTANCE: invention pertains to the method of obtaining 1,2,4-triphenylbenzol, which can be used in thin chemical synthesis industry, pharmaceuticals and as a plasticiser. The method involves preliminary formation of an inert gas (argon, nitrogen) in the atmosphere, in a medium of a nickel (I) toluene complex NiCp(PPh3)2 through reaction of 1 molar part of the nickel complex (0) Ni(PPh)4 with 1 molar part of Ni(Cp)2 complex for a period of 20-30 minutes at 20-25°C, after which phenylacetylene is added to the obtained toluene solution. Molar ratios phenylacetylene:toluene:Ni = 200:400:1. The cyclotrimerisation reaction of phenylacetylene is carried out at 20°C and atmospheric pressure. ^ EFFECT: simplification of the method and increased output of the target product. ^ 1 ex
