Manganese(III)-mediated direct phosphonylation of arenes

Manganese (III)-promoted direct phosphonylation of mono- and disubstituted arenes with dialkylphosphite afforded regioselective dialkylphosphonates in good yields. The reactions can apply to arenes bearing electron-donating groups and electron-withdrawing

Naphthalocyanine compound and production thereof

Disclosed is a novel naphthalocyanine compound which strongly absorbs light or near infrared region and which is chemically stable and highly soluble to an organic solvent. The naphthalocyanine compound is represented by the following formula [1]; STR1 wh

Oxidative Phoshonylation of Aromatics with Ammonium Cerium(IV) Nitrate

Arylphosphonates 5 and 6 can be prepared in good yields in a one-step synthesis starting from arenes with tri- or diethylphosphites and cerium ammonium nitrate (CAN) as oxidant.The seletivity of the oxidative phosphonylation is relatively low; the reactive species is a phosphite radical cation.

OXIDATIVE PHOSPHONYLATION OF AROMATIC COMPOUNDS

Aryl phosphonates can be prepared in good yield from the respective arenes and tri- or dialkylphosphites by either chemical or anodic oxidation.The anodic oxidation proceeds either via phosphinium radical cations, which then attack the arenes electrophilically, or via arene radical cations, which add the trialkylphosphite as nucleophile.Aryl phosphonates are also obtained in good yield by chemical oxidation with peroxodisulfate/AgNO3 in acetonitrile/water or glacial acetic acid.The diethylphosphinium radical cation, formed from diethylphosphite by oxidation with Ag(II), is supposed to be the reactive species in this process.Raising the silver salt concentration leads to an increase in polyphosphonylation.Selectivity ratios were determined for the oxidative phosphonylation process.
