dialkylation - Wiktionary

Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion, or a carbene (or their equivalents). Alkylating agents are reagents for effecting alkylation. Alkyl groups can also be removed in a process known as dealkylation. Alkylating agents are often classified according to their nucleophilic WebDec 8, 2024 · To demonstrate the power of this highly selective N-alkylation methodology, we fully converted a variety of amino acids such as glycine ( 1b ), alanine ( 1c ), valine ( … WebApr 7, 2024 · Schematic representations of human antibody structures and attached glycans.
