Descrição geral

Phosphorus pentoxide is a deliquescent compound prepared by reacting phosphorus with air. It is a commonly used as dehydrating and condensing agent in organic synthesis.[1]

Aplicação

Dehydrating agent used for halogenation with tetrabutylammonium halides.

Process for Producing Halogenated Heteroaryl Compounds

Phosphorus pentachloride has been used for the vaccum distillation of 1-methyl-2-pyrrolidinone (NMP), which was employed as mobile phase in a chromatographic analysis.[2]

It may be used as one of the reaction components in the synthesis of dichlorine heptoxide (Cl₂O₇)[3] and transition-metal phosphides (Ni₂P, Co₂P and MoP).[4] P₂O₅ supported on alumina can be used for the solvent-free and microwave-assisted preparation of 1, 5-benzodiazepine analogs.[5] P₂O₅/KX (X = Br, I) reagent system may be used for the transformation of alcohols into the corresponding alkyl iodides and bromides.[6]

Phosphorus pentoxide/methanesulfonic acid (PPMA) may be used as a condensing agent and solvent for the synthesis of:

• High molecular weight poly(benzoxazole)s via direct polycondensation of aromatic dicarboxylic acids containing phenyl ether structure with 3,3′-dihydroxybenzidine dihydrochloride.[7]

• Aromatic poly(phenylene ether ether ketone)s via direct self-polycondensation of 4-(4′-phenoxyphenoxy)benzoic acids.[8]

• 1,3-1H-dibenzimidazole-benzene by the reaction of isophthalic acid with 1,2-diaminobenzene.[9]
