Diimines are
organic compounds containing two
imine (RCH=NR') groups.
Common derivatives are 1,2-
diimines and 1,3-
diimines.
These compounds are used as...
- Diimide, also
called diazene or
diimine, is a
compound having the
formula HN=NH. It
exists as two
geometric isomers, E (trans) and Z (cis). The term diazene...
-
molecules condense with the two
carbonyl groups to give a
diimine: In the
second stage, this
diimine condenses with the aldehyde: However, the
actual reaction...
- a
cyclic [3,3]-sigmatropic
rearrangement occurs producing a
diimine. The
resulting diimine forms a
cyclic aminoacetal (or aminal),
which under acid catalysis...
- to a
variety of
bulky ligands.
Condensation with
glyoxal gives the 1,2-
diimine ligands. An
example is glyoxal-bis(mesitylimine), a
yellow solid that is...
-
catalysts upon
complexation to late
transition metals.
Examples are β-
diimine, α-keto-β-
diimine, amine-imine and most
recently diamine ligands. As the vast majority...
- The enol is
about 1 kcal/mol more
stable than the ****to form.
Numerous diimine and
dioxime ligands have been
prepared from this ****tone. It also condenses...
- some cases,
HNacNacs also
serve as charge-neutral 1,3-
diimine ligands.
NacNac ligands are
diimine analogues of
acetylacetonate ligands. An intermediate...

synthesized by
condensation of 2,4,6-trimethylaniline and
