11difluoroethyl

11difluoroethyl refers to a chemical fragment or substituent group. It is derived from the ethyl group by replacing two hydrogen atoms with fluorine atoms. The designation "1,1" indicates the positions of the fluorine atoms on the ethyl chain. Specifically, both fluorine atoms are attached to the same carbon atom, which is the first carbon atom of the ethyl group when it is considered as a substituent. The structure can be represented as -CF2CH3.

This difluoroethyl group can be incorporated into larger organic molecules. The presence of fluorine atoms significantly alters the chemical and physical properties of the molecule compared to its non-fluorinated analog. Fluorine is highly electronegative, which can lead to increased polarity and altered reactivity. The carbon-fluorine bond is also very strong, contributing to increased thermal and chemical stability.

Compounds containing the 1,1-difluoroethyl group may find applications in various fields depending on the overall structure of the molecule. These can include pharmaceuticals, agrochemicals, and materials science. For example, the introduction of fluorine can influence a drug's metabolic stability, lipophilicity, and binding affinity to biological targets. In materials, fluorinated groups can impart properties such as low surface energy, hydrophobicity, and resistance to degradation. The specific synthesis and properties of any compound containing this moiety would depend on the broader molecular context.
