Research Article

Aerobic Photooxidative Carbon–Carbon Bond Formation between Tertiary Amines and Carbon Nucleophiles

Itoh et al. have reported the aerobic photooxidative carbon–carbon bond formation between tertiary amines and carbon nucleophiles. According to their results, in the presence of molecular oxygen and 2-chloroanthraquinone catalyst, 2-aryl-1,2,3,4-tetrahydroisoquinoline reacts with carbon nucleophiles such as nitroalkanes to form a carbon–carbon bond by the visible-light irradiation promoted radical process. This reaction can be expected to be an environmentally-friendly catalytic oxidation method because it uses an organic photocatalyst with molecular oxygen as the terminal oxidant and visible light from a general-purpose fluorescent lamp.

Product Highlight

Difluorocarbene Precursor for Difluoromethylation

Diethyl (Bromodifluoromethyl)phosphonate is a difluorocarbene precursor. The P-C bond can be hydrolyzed by KOH at -78 °C to room temperature to generate difluorocarbene (:CF2). When using phenols as substrates, the corresponding difluoromethyl ethers can be obtained via difluoromethylation in good yields. This reaction proceeds under very mild conditions, thus, even phenols bearing enolizable groups can be difluoromethylated at their phenolic hydroxy groups.

Chromatography -Analysis of Adenosine phophates (AMP, cAMP, ADP, ATP) by TCI Dual series

TCI Dual series can analyze hydrophilic compounds without any of the ion-pair reagents that are required for ODS columns, because the TCI Dual series consists of both ODS ligands and Ion-exchange ligands.
This application is also suitable for LC/MS by using volatile buffers.
