The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Photochemistry of 1,5-Cyclooctadiene Platinum Complexes for Photoassisted Chemical Vapor Deposition》. Authors are Liu, Hanwen; Brewer, Christopher R.; Walker, Amy V.; McElwee-White, Lisa.The article about the compound:Dichloro(1,5-cyclooctadiene)platinum(II)cas:12080-32-9,SMILESS:C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-]).Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II). Through the article, more information about this compound (cas:12080-32-9) is conveyed.
Quantum yields for disappearance of (COD)PtMe2 (1a) and (COD)PtMeCl (1b) were determined at 334 nm in C6D6 solvent. Chain reactions initiated by formation of a Me radical were proposed to be the cause of quantum yields higher than unity (Φ = 5.52 ± 0.40 for 1a) when the reaction mixtures included C4F9I. The chain reactions were suppressed in the presence of the radical trap 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO), which resulted in measured disappearance quantum yields of Φ = 0.037 ± 0.003 for (COD)PtMe2 and Φ = 0.44 ± 0.02 for (COD)PtMeCl at 334 nm. Weak luminescence was observed for 1a and 1b, and it was determined that emissive decay is not competitive with Pt-CH3 bond homolysis. DFT studies enabled assignment of both SBLCT and MLCT transitions in the UV/vis spectra of 1a, while 1b only exhibits MLCT transitions. These effects can be attributed to the symmetry of the mol. and its electronic structure.
As far as I know, this compound(12080-32-9)Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II) can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
