WebSynthesis. Silyl enol ethers are generally prepared by reacting an enolizable carbonyl compound with a silyl electrophile and a base, or just reacting an enolate with a silyl electrophile. Since silyl electrophiles are hard and silicon-oxygen bonds are very strong, the oxygen (of the carbonyl compound or enolate) acts as the nucleophile to form a Si-O … WebJan 18, 2024 · Nitroalkylation of trinitroquinolone 16 is also achieved by using a nitroalkane as a carbon nucleophile in the presence of triethylamine . While primary nitroalkanes undergo cine -substitution efficiently at room temperature, secondary nitroalkanes with steric hindrance are less reactive, requiring longer reaction times and affording relatively …

All amines contain an active … WebJun 5, 2024 · Triethylamine. Amines can be nucleophiles or bases. Increasing their steric bulk near the nitrogen atom diminishes their nucleophilicity while retaining the basicity. …
WebNon-nucleophilic base. As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile. Normal bases are also nucleophiles, but … WebThis could happen because the nucleophile was too stable and was not able to replace the leaving group in the substrate. The second set of the reactions was between …
WebApr 13, 2024 · A base, such as triethylamine, serves as interim storage for the thiol proton before it is transferred to the warhead. By deprotonating the thiol prior to the nucleophilic attack, the nucleophilicity of MeSH is strongly increased, thereby decreasing the associated activation barriers considerably (Figures S22C, S23B and S24A–C).
