TL;DR: Negative ion photoelectron spectroscopy and gas-phase proton transfer kinetics were employed to determine the CH bond dissociation energies of acetylene, ethylene, and vinyl radical.

TL;DR: In this paper, rate coefficients have been measured for the gas phase reactions of methyl, ethyl, n-propyl, isopropyl, tert-butyl, and neopentyl chlorides and bromides with the following set of nucleophiles, listed in order of decreasing basicity.

TL;DR: In this paper, the gas-phase acidities of 15 simple alkanes were determined in a flowing afterglow-selected ion flow tube (FA-SIFT) by a kinetic method in which alkyltrimethylsilanes were allowed to react with hydroxide ions to produce a mixture of trimethylsiloxide ions by loss of alkane and alkyldimethyl-siloxide ion by losing of methane.

TL;DR: In this paper, the authors used negative ion photoelectron spectroscopy to determine gas phase acidity values by proton transfer reactions for systems in which isomerization can occur.

TL;DR: In this paper, a linear correlation was established for loss of substituents of known acidity (CH4, H2, C2H4, C6H6), which allowed the acidity of several alkanes to be predicted, as well as the electron affinity of the corresponding alkyl radicals.
