- Аннотация: Thermolytic decomposition of 3,3'-(ethan-1,2-diyl)bis(1-methyl-1H-imidazolium) bis-(hexafluorophosphate) (1) under reduced pressure results in a 1 : 1 mixture of pentafluoro(1-ethenyl-3-methyl-2,3-dihydro-1H-imidazole-2-ylidene-kC2)phosphorous (2) and penta fluoro(3-methyl-1H-imidazole-kN3)phosphorous (3) in an almost quantitate yield. Products 2 and 3 were isolated as individual compounds by fractional recrystallization from hot methanol. Direct observation of a 1 : 1 co-crystallite of 2-pentafluorophosphanyl-1-ethenyl-3-methyl-1H-imidazolium hexafluorophosphate and adduct 2 (compound 5) as a minor coproduct of this reaction reveals a complicated path of the thermolysis. Crystal and molecular structures of compounds 2, 3, and 5 were established by X-ray diffraction analysis. Compound 2 presents the first example of an N-alkenyl substituted Arduengo carbene adduct with a main Group element Lewis acid. Compound 3 presents the second known organic base N-adduct with PF5.
