  • Nucleophilic addition — In organic chemistry, a nucleophilic addition reaction is an addition reaction where in a chemical compound a π bond is removed by the creation of two new covalent bonds by the addition of a nucleophile.[1] Addition reactions are limited to… …   Wikipedia

  • Nucleophilic conjugate addition — is a type of organic reaction. Ordinary nucleophilic additions or 1,2 nucleophilic additions deal mostly with additions to carbonyl compounds. Simple alkene compounds do not show 1,2 reactivity due to lack of polarity, unless the alkene is… …   Wikipedia

  • Nucleophilic acyl substitution — describes the substitution reaction involving nucleophiles and acyl compounds. Acyl compounds are carboxylic acid derivatives including esters, amides and acid halides. Nucleophiles include anionic reagents such as alkoxide compounds and enolates …   Wikipedia

  • Addition reaction — An addition reaction, in chemistry, is in its simplest terms an organic reaction where two or more molecules combine to form a larger one.There are two main types of polar addition reactions: * Electrophilic addition * Nucleophilic addition Other …   Wikipedia

  • Nucleophilic substitution — In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron nucleophile selectively bonds with or attacks the positive or partially positive charge of an atom or a group of atoms called… …   Wikipedia

  • Nucleophilic aromatic substitution — A nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring. There are 6 nucleophilic substitution mechanisms encountered with …   Wikipedia

  • addition reaction — Chem. a reaction in which part of a compound is added to one end of a double or triple bond, while the rest adds to the other end, converting it, respectively, to a single or double bond. * * * ▪ chemical reaction       any of a class of chemical …   Universalium

  • Organostannane addition — reactions comprise the nucleophilic addition of an allyl , allenyl , or propargylstannane to an aldehyde, imine, or, in rare cases, a ketone[1]. Organostannane addition to carbonyl groups constitutes one of the most common and efficient methods… …   Wikipedia

  • Tetrahedral carbonyl addition compound — A tetrahedral carbonyl addition compound is an organic compound formed by nucleophilic addition to a carbonyl compound such as an aldehyde or ketone. This provides the carbon with four temporary bonds, one of which is broken when the leaving… …   Wikipedia

  • Radical-nucleophilic aromatic substitution — or SRN1 in organic chemistry is a type of substitution reaction in which a certain substituent on an aromatic compound is replaced by a nucleophile through an intermediary free radical species:The substituent X is a halide and nucleophiles can be …   Wikipedia
