In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. They are classified as imine derivatives because they are formed from the reaction of an aldehyde or ketone with the terminal -NH 2 group of semicarbazide, which behaves very similarly to primary amines .

2022年2月28日 · A semicarbazone is a compound that has the following general structural formula. R 1 and R 2 could be hydrogen atoms, alkyl groups, aryl groups, or any combination thereof. eg:

α-Oxo semicarbazone chemistry is the condensation reaction between α-oxo aldehyde-functionalized ligands and a semicarbazone-functionalized surface (Fig. 5.9).

2011年9月20日 · Thiosemicarbazone and semicarbazone analogues are important and privileged moieties in several compounds presenting a wide range of biological proprieties. Moreover, these groups are synthetically available and structurally varied in the medicinal chemistry field.

2024年1月5日 · Two semicarbazone-based derivative ligands, ortho-naphthalldehyde disemicarbazone (L1) and dehydrozingerone semicarbazone (L2), have been combined with copper chloride salt to develop a novel copper (II) heteroleptic complex.

semicarbazone: ChEBI ID CHEBI:87210: Definition A hydrazone resulting from the formal condensation of an aldehyde or ketone with the non-acylated nitrogen of semicarbazide or its substituted derivatives. Stars

A semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. They are classified as imine derivatives because they are formed from the reaction of an aldehyde or ketone with the terminal NH2 group of semicarbazide

Semicarbazone and its metal complexes play the significant role in an industrial, pharmaceutical, and agricultural chemistry. They are also used as polymers, dyes, and as catalysts in different biological systems, like Schiff base ligands.

A new semicarbazone derivative, phenyl semicarbazone is synthesized by using N,N,- bis (2- chloroethyl)aminobenzaldehyde). Semicarbazones are an important compounds obtained by condensation of semicarbazides with suitable aldehyde or ketones. Synthesis of new semicarbazones always plays a new role in many fields like chemical,

When a semicarbazide is added to the carbonyl group of ketones or aldehydes, the product is called semicarbazone. Let’s have a look at the semicarbazide addition to cyclobutanone: As we can see that firstly, electrophilic centres are created at carbon by protonation of oxygen atoms.
