Ketone α-alkylation at the more-hindered site
Nature Communications, 2023 Control of the regioselectivity of α-alkylation of carbonyl compounds is a longstanding topic of research in organic chemistry. By using stoichiometric bulky strong bases and carefully adjusting the reaction conditions, selective alkylation of ...

Alkylation of Dihydrofullerenes [PDF]
The Journal of Organic Chemistry, 2002 The fulleride dianions C(60)(2-) and C(70)(2-) were generated by deprotonation of the corresponding hydrogenated fullerenes, 1,2-C(60)H(2) and 1,2-C(70)H(2). These anions were prepared in the presence of a variety of alkylating agents, and mono- or dialkylated products were obtained. Alkylation was not successful with sulfonate ester alkylating agents.

Copper(I)-catalyzed asymmetric alkylation of α-imino-esters
Nature Communications, 2023 Asymmetric alkylation of enolates is one of the most direct and important reactions to prepare α-chiral carbonyl compounds. Except for the classical methods that rely on the use of chiral auxiliaries, asymmetric catalysis emerged as a powerful tool ...

Kinetic modeling of liquid phase catalytic alkylation of guaiacol with cyclohexene
Chemical Engineering Journal Advances, 2021 The kinetics of the liquid-phase alkylation of guaiacol (G) with cyclohexene (CH) over Amberlyst 36 resin was studied using Langmuir–Hinshelwood–Hougen–Watson (LHHW) heterogeneous kinetic models.

Alkyl–Alkyl Suzuki Cross‐Coupling of Unactivated Secondary Alkyl Chlorides [PDF]
Angewandte Chemie, 2010 The first method for achieving alkyl–alkyl Suzuki reactions of unactivated secondary alkyl chlorides has been developed. Carbon–carbon bond formation occurs under mild conditions (at room temperature) with the aid of commercially available catalyst components.
