The first isolation of 1,3-diaza-2-sila-4-cyclopentene radical cation salt: The X-ray structure and electronic properties
The first TPFPB salt of 1,3-diaza-2-sila-4-cyclopentene (DASCP) radical cation was isolated as an orange crystalline solid by one-electron oxidation of the neutral DASCP with Ag(I) ion. The X-ray structural analysis and theoretical studies showed that the silicon atom plays an important role in stabilization of this cationic species.
