1,2-Cyclohexanedione Chemical Properties,Usage,Production

Chemical Properties

clear yellow liquid after melting

Uses

1,2-Cyclohexanedione is utilized as a substrate to study enzyme cyclohexane-1,2-dione hydrolase, which is a new tool to degrade alicyclic compounds. It also acts as a specific reagent for arginine residues.

Uses

1,2-Cyclohexanedione have been used as a substrate to study enzyme cyclohexane-1,2-dione hydrolase as a new tool to degrade alicyclic compounds.

Definition

ChEBI: Cyclohexane-1,2-dione is a cyclohexanedione carrying oxo substituents at positions 1 and 2.

Reactions

1,2-Cyclohexanedione may effectively occupy vacant coordination sites and thus promote the present cycloisomerization[1]. Tanaka et al. research the catalytic cycloisomerization of 1,6- and 1,7-diynes leading to trienes and vinylpyrroles by using a cationic rhodium(I)/Segphos complex (2.5-10 mol %) and 1,2-cyclohexanedione (100 mol %).
