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...
- metallo-intercalator and the DNA sequence. For example, the
ligand 5,6-chrysenequinone
diimine (chrysi) and its
analogues are
designed to be too wide to fit
inside the...
-
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...
-
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...
- 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...
- 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
glyoxal to give the
diimine. In the
presence of acid, the
resulting glyoxal-bis(mesitylimine) condenses...
- the
diamine condenses with 4-Trifluoromethylbenzaldehyde to give to the
diimine. The
salen ligands, some of
which are used in catalysis, are
derived from...
