TL;DR: A charge-shift type of photoinduced electron-transfer reactions from various electron donors to the singlet excited state of 10-decylacridinium cation (DeAcrH+) in a nonpolar solvent (benzene) is found to be as efficient as those of MeACrH+) and DeA CrH+ in a polar solvent (acetonitrile).
Abstract: A charge-shift type of photoinduced electron-transfer reactions from various electron donors to the singlet excited state of 10-decylacridinium cation (DeAcrH+) in a nonpolar solvent (benzene) is found to be as efficient as those of 10-methylacridinium cation (MeAcrH+) and DeAcrH+ in a polar solvent (acetonitrile). Irradiation of the absorption bands of MeAcrH+ in acetonitrile solution containing tetraalkyltin compounds (R4Sn) results in the efficient and selective reduction of MeAcrH+ to yield the 10-methyl-9-alkyl-9,10-dihydroacridine (AcrHR). The same type of reaction proceeds in benzene when MeAcrH+ is replaced by DeAcrH+ which is soluble in benzene. The photoalkylation of R‘AcrH+ (R‘ = Me and De) also proceeds in acetonitrile and benzene using 4-tert-butyl-1-benzyl-1,4-dihydronicotinamide (ButBNAH) instead of R4Sn, yielding MeAcrHBut. The quantum yield determinations, the fluorescence quenching of R‘AcrH+ by electron donors, and direct detection of the reaction intermediates by means of laser flash p...

TL;DR: In this article, the kinetics of pyrolysis of pyridine dilute in argon have been studied in a single-pulse, shock tube, using capillary column GC together with GC/MS and FTIR spectroscopy for product determination, over the temperature range of 1,300-1,800 K and total pressures of 7-11 atm.
Abstract: The kinetics of pyrolysis of pyridine dilute in argon have been studied in a single-pulse, shock tube, using capillary column GC together with GC/MS and FTIR spectroscopy for product determination, over the temperature range of 1,300-1,800 K and total pressures of 7-11 atm. At the lower end of the studied temperatures, cyanoacetylene was found to be the principal nitrogen-containing product. At elevated temperature hydrogen cyanide predominated. Other major products were acetylene and hydrogen. Several sources of HCN were identified in the system. An important source of HCN at high temperatures is the addition of H atoms to cyano compounds, especially cyanoacetylene, but also acetonitrile and acrylonitrile which are produced in the pyrolysis. The pyrolysis is a chain process initiated principally by C-H bond fission to form o-pyridyl. A 58-step reaction model is presented and shown to substantially fit the observed profiles of the major product species.
