Abstract:
A computational analysis of the CO2RR yielding challenging alcohol products was performed over fcc and unconventional hcp-Cu nanoparticles. The methanol formation was found to be exceptionally challenging due to excessive formate stability, CO* accumulation and more favorable C-C coupling, whereas hcp-Cu(110)h could promote ethanol formation via an uncommon OC-CHO intermediate.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
