salicylaldehyde

The thermal fragmentation of salicylaldehyde was studied from two aspects.

They are prepared from a salicylaldehyde and a monoamine.

Another example is making salicylaldehyde (not shown above).

The name salen is a contraction for salicylaldehyde and ethylenediamine.

Numerous types of salen are derived from salicylaldehyde or the diamine.

A common way to produce the 3-azidocoumarin is by condensation of salicylaldehyde and N-acetylglycine or nitroacetate.

Similar reactivity with substituted salicylaldehyde derivatives gave the corresponding Schiff bases 2–6.

The synthesis is achieved by a condensation reaction of the diamine with salicylaldehyde:

The phenoxide derivative is susceptible to formylation paraformaldehyde to give salicylaldehyde.

It is the oxime of salicylaldehyde.

For instance, the altered reaction with phenol would yield salicylic acid rather than the expected product, salicylaldehyde.

Salen ligands are prepared by the condensation of a salicylaldehyde with an amine.

In practice, the reaction of the salicylaldehyde with the amine in alcoholic solvent usually goes to completion.

Schiff base derivatives, such as those derived from salicylaldehyde, are excellent chelating ligands.

Boron chelates obtained from salicylaldehyde and 2prime-hydroxyacetophenone azines are colored compounds with potential applications in analytical chemistry.

Key words: Schiff base, macrocycle, condensation, salicylaldehyde, conjugated.

Coumarin can be prepared by a number of name reactions with the Perkin reaction between salicylaldehyde and acetic anhydride being a popular example.

O-alkylation of salicylaldehyde with chloroacetic acid followed by dehydration of the resulting ether.

The condensation of salicylaldehyde and ethylenediamine give families of imine-containing chelating agents such as salen.

For salicylaldehyde, the arrangement is taken as the reference conformer, with a computed energy of 25.7 kJ/mol relative to the hydrogen-bonded structure.

Condensation of equimolar amounts of salicylaldehyde, N-hydroxypiperidine, and phenylboronic acid yields the title compound.

STO 3G MO calculations give an optimized planar structure for salicylaldehyde.

Three boronates have been synthesized by reaction of tridentate azomethine ligands derived from salicylaldehyde with phenylboronic acid.

Abstract: 1H nmr spectral parameters are reported for salicylaldehyde and 15 of its derivatives in dilute CCl4 solutions.

The ultraviolet–visible, infrared, and Raman spectral characteristics of some anils of benzaldehyde and salicylaldehyde in several solvents have been investigated.
