The steric effect of a trifluoromethyl group.

Chemical and Pharmaceutical Bulletin, 1991
In the study of ene reaction of trifluoromethyl ketones, a trifluoromethyl group was found to behave as a much larger substituent than commonly believed. Similar results were obtained in the dehydration of trifluoromethyl homoallyl alcohols.

Effect of Alkyl Substituents on the Hydrogen Bonding and Molecular Structure of Benzophenylhydroxamic Acids Crystal structure of UO2 Complex of p-Isopropylbenzophenylhydroxamic Acid [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1995
The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic

Steric hindrance induced low exciton binding energy enables low‐driving‐force organic solar cells

Aggregate
Exciton binding energy (Eb) has been regarded as a critical parameter in charge separation during photovoltaic conversion. Minimizing the Eb of the photovoltaic materials can facilitate the exciton dissociation in low‐driving force organic solar cells ...

Directed synthesis of N1/N3-histidine modified by 2-hydroxyethylthioethyl and identification in sulfur mustard-exposed plasma

Communications Chemistry
Sulfur mustard (HD) alkylates biomolecules such as proteins, generating specific biomarkers. This study employs steric hindrance, electronic effects, and solvent effects through an occupancy-removal strategy to synthesize regioisomers [N1-HETE]-His and ...
