Nitrosyl chloride tribromide

A reaction deals with the preparation of 4-halogenated pyridinecarboxylic acids (X-240) from 4-nitronicotinic acid-1-oxide (X-239) by explosive interaction with phosphorous trichloride or tribromide The requisite formation of nitrosyl chloride is not recorded. The 4-iodoacid (X-240, X = I) was prepared from the chloro-acid with hydrogen iodide. The authors also report... [Pg.304]

Iodine heptafluoride, isocyanates, nitrosyl perchlorate, perchlorates, platinum, potassium- er -butoxide, potassium, potassium oxide, potassium peroxide, phosphonis(III) oxide, silver nitrate, silver oxide, sulfuric acid, oleum, sodium, sodium hydrazide, sodium peroxide, sulfmyl cyanamide, tetrachlorosilane, i-triazine-2,4,6-triol, triethoxydialuminum tribromide, triethylaluminum, uranium fluoride, xenon tetrafluoride. Mixture with mercury nitrate(II) forms explosive mercury fulminate. Forms explosive complexes with perchlorates, magnesium perchlorate (forms ethyl perchlorate), silver perchlorate. Flow or agitation of substance may generate electrostatic charges due to low conductivity. [Pg.1]
