the range of coverage from 0 to 0.07 monolayer, Measured values of the surface-diffusion activation energy range from 8 to 17 kilocalories per mole depending on the degree of coverage and the crystal lographic orientation of the substrate under the condition of zero electric field at the ...
Criterion of Mechanism based on Optical Rotation and Rearrangement in Alkyl Groups during Formation of Alkyl HalidesTHE geometrical and electronic requirements of replacement reactions designated S N 2, S N 1 and S N i were described by Ingold and Hughes on the basis of kinetics and changes in ...
Novel strategy for acid chlorides formation that do not use carboxylic acids is particularly attractive in chemical synthesis but remains challenging. Herein, we reported the development of a highly effective Pd-catalyzed hydrochlorocarbonylation of alkenes with CO for the formation of alkyl acid chlorid...

A protonation of t-BuC60- with trifluoroacetic acid can also occur to give 1,4-t-Bu(H)C60, which rearranges rapidly to yield 1,2-t-Bu(H)C60. Rate constants for the second alkylation of t-BuC60- with a variety of different alkyl halides are compared with values of genuine SN2 ...
One useful reaction of these enolates is that they will perform SN2 reactions on alkyl halides, forming a new C-C bond. This is called, “alkylation”. The products can then be made to lose CO2 (decarboxylation) in a process known as the malonic ester synthesis (for di-esters) or aceto...
A process by which alkyl halides may be reacted (coupled) with nucleophilic materials in the presence of a homogeneous catalyst system. The process comprises reacting (coupling) alk
