General Description

Phosphoric acid, 2-naphthalenyl diphenyl ester, also known as diphenyl 2-naphthyl phosphate, is a chemical compound that has applications in material science, particularly in flame retardancy. Its synthesis involves an esterification reaction between phosphoric acid and 2-naphthol. This chemical is categorized as an organophosphorus compound, characterized by a phosphorus atom bonded with carbon. As an ester, it falls under the class of organic compounds that result from condensation of acids and alcohols. It possesses strong effectiveness in enhancing flame retardancy, and hence used in manufacturing materials that demand high fire resistance. Careful handling of this chemical is recommended as it may pose health risks upon exposure.

Phosphorylation Organocatalysts Highly Active by Design

The activity of nucleophilic organocatalysts for alcohol/phenol phosphorylation was enhanced through attaching oligoether appendages to a benzyl substituent on imidazole- or aminopyridine-based active units, presumably because of stabilizing n-cation interactions of the ethereal oxygens with the positively charged aza-heterocycle in the catalytic intermediates, and was substantially higher than that of known benchmark catalysts for a range of substrates. Density functional theory calculations and the study of analogues having a lower potential for such stabilizing interactions support our hypothesis.

Organocatalytic phosphorylation of alcohols using pyridine- N -oxide

Phosphorylation of alcohols by phosphoryl chlorides catalysed by pyridine-N-oxide is reported. The utility of this method is demonstrated through phosphorylation of primary, secondary and a tertiary alcohol as well as phenols under mild reaction conditions and with low catalyst loading (5 mol%).
