Organometallic compounds of electropositive metals are superbases, but they are generally strong nucleophiles. Examples include organolithium and organomagnesium ( Grignard reagent ) compounds. Another type of organometallic superbase has a reactive metal exchanged for a hydrogen on a heteroatom , such as oxygen (unstabilized alkoxides ) or ...
Initial electronic structure calculations of aluminium(I) nucleophiles were gained using ab initio calculations. Cimpoesu and coworkers analyzed the first monomeric aluminium(I) compound by plotting the contour map of the Laplacian of the electron density inside the molecule and found that there is indeed a lone pair localized on the aluminium ...
A hydroxide ion acting as a nucleophile in an S N 2 reaction, converting a haloalkane into an alcohol. In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Because nucleophiles donate electrons, they ...
This is a list of animated films aimed primarily at children.The films are designed to hold children's attention and often have an educational dimension, particularly around cultural values, This list has all the animated films that are always dubbed in North-West Europe, Poland, Portugal, Balkan, Baltic and Nordic countries, where generally only kids movies and kids TV shows (including all ...
If looked at from the point of view of an S N 2 reaction this would seem counterintuitive, since the C-F bond is amongst the strongest in organic chemistry, when indeed the fluoride is the ideal leaving group for an S N Ar due to the extreme polarity of the C-F bond. Nucleophiles can be amines, alkoxides, sulfides and stabilized carbanions. [5]

In the addition of a nucleophile (Nu) attack to a carbonyl, the BD angle is defined as the Nu-C-O bond angle. The BD angle adopted during an approach by a nucleophile to a trigonal unsaturated electrophile depends primarily on the molecular orbital (MO) shapes and occupancies of the unsaturated carbon center (e.g., carbonyl center), and only secondarily on the molecular orbitals of the ...
