Perchloryl benzene

The nitration product of perchloryl benzene is explosive, comparable in shock-sensitivity with lead azide, with a very high propagation rate. 

This was obtained [46] by nitrating perchloryl benzene with a nitrating mixture of anhydrous nitric acid and sulphuric acid. It forms pale yellow needles with a m.p. of 49-50°C. 

By comparison to the other chlorine oxyfluorides, perchlo-ryl fluoride is a mild fluorinating agent and has been used for the preparation of fluorinated steroids. FCIO3 also reacts with phenyl lithium to form the unstable perchloryl benzene, C6H5CIO3, and lithium fluoride. 

The pyrrolidine enamines of /l -3.]cetosteroids (111), on alkylation with methyl iodide, gave mainly the N-alkylated product (5,55) in nonpolar solvents such as benzene. The reaction in more polar solvents gave the 4-methylated product (5.S). The reaction of (111) with perchloryl fluoride involves attack at the C-4 atom to give, after acid hydrolysis, either 4-fluoro-zJ -3-ketone (119) or 4,4-difluoro-zJ -3-ketone 120), depending on the reaction conditions (59).

Group 16 (VIA) Perchlorates. A perchlorate compound perchloryl sulfate, [CAS 43059-05-8], SO GO was produced by the low temperature electrolysis of a I2-WH2SO4 and 3-.VHQ04 solution. This compound is a strong oxidizer reaction with toluene, acetone, benzene, or alcohol at room temperature produces an exothermic and explosive reaction. The S04(C104)2 is soluble in Freon and CC14 without reaction.

Perchlotylation. Pennsalt chemists found that when perchloryl fluoride is bubbled into a suspension of aluminum chloride in benzene a reaction analogous to a Friedel-Crafts reaction occurs and gives perchlorylbenzene, a colorless liquid. 

Preparation of a-ftuoroketones and vinylogs. Gabbard and Jensen" of the Ben May Laboratory of Cancer Research converted cholestanone into the pyrrolidyl-enamine and bubbled perchloryl fluoride into a benzene solution of this derivative until an initial orange color was discharged (30 sec.). Workup and crystallization afforded 2o -fluorocholestane-3-one in good yield. Joly and Wamant" studied the... 

ANILINE (62-53-3) Combustible liquid (flash point 158°F/70°C). Unless inhibited (usually by methanol), readily able to polymerize. Violent reaction, including the possibility of fire, explosion, and the formation of heat- or shock-sensitive compounds may result from contact with acetic anhydride, benzene diazonium-2-carboxylate, aldehydes, alkalis, benzenamine hydrochloride, boron trichloride, l-bromo-2,5-pyrrolidinedione, chlorosulfonic acid, dibenzoyl peroxide, fluorine nitrate, halogens, hydrogen peroxide, isocyanates, oleum, oxidizers, organic anhydrides, ozone, perchloryl fluoride, perchromates, potassium peroxide, P-propiolactone, sodium peroxide, strong acids, trichloromelamine. Strong reaction with toluene diisocyanate. Reacts with alkaline earth and alkali metals. Attacks some plastics, rubber, and coatings. Incompatible with copper and copper alloys.

As a reinvestigation has revealed, phenyllithium reacts instantaneously and completely with perchloryl fluoride. However, it is difficult to separate it from petroleum ether, tetrahydrofuran, and other standard solvents. Despite similar boiling points, fluorobenzene (bp 85 °C) is far more volatile than benzene (bp 80 °C). Even most careful...
