Abstract:
A study of the reaction of [Ni(NHC)2] synthons with the heterocumulene CS2 is reported. Nickel complexes of η2-(C-S) side-on coordinated CS2, [Ni(NHC)2(η2-CS2)] (NHC = IiPrMe (1a), IiPr (1b)) were obtained from the reaction of CS2 with precursors of [Ni(NHC)2] (NHC = IiPrMe, IiPr). The result of this reaction critically depends on the NHC employed, as [Ni(IMes)2], the complex of the sterically more demanding N-aryl substituted NHC IMes, led to formation of the dinuclear complex [{Ni(IMes)(μ2-CS2)}2] (2d). The related compound [{Ni(IDipp)(μ2-CS2)}2] (2c) was isolated from the reaction of [Ni(IDipp)(η6-C7H8)] with CS2. If [Ni(cAACMe)2] was used, insertion of CS2 into the cAAC carbon nickel bonds occurs and the bis-(azolium-2-dithiocarboxylate) complex [Ni(cAACMe-CS2)2] (3e) was formed.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
