Abstract

Substituted polyhalocyclopentadienes are produced by reacting a polyhalocyclopentadiene or a polyhalocyclopentene with a neutral ester or a neutral ester amide of a phosphorous, phosphinous or phosphonous acid or the corresponding thio compound, subjecting the reaction mixture to a solvolysis with water, an alcohol, a phenol, a mercaptan, ammonia or a primary or secondary amine, and separating the phosphoric acid derivative formed from the substituted polyhalocyclopentadiene(s) according to known methods. In examples, starting materials used are selected from hexachloro-,1,2,3,4,5-pentachloro- and 2,3,4,5-tetrachloro-cyclopentadiene, octachlorocyclopentene and ethylpentachlorocyclopentadiene, while isolated products are ethyl-, n- and i-propyl-, n-butyl, cyclohexyl- and 2-methoxy-ethyl-pentachlorocyclopentadienes, diethyl and di-n-butyltetrachlorocyclopentadienes, mono-and di-n-butyltrichlorocyclopentadienes and ethyl a -pentachlorocyclopentadienylpropionate. The following specific by-products were also isolated, the respective reagents being indicated in parentheses:-diethyl, di-n-propyl and di-n-butylphosphates (trialkylphosphites, water); tri-n-butylphosphates (tributylphosphite, butanol); phenyldiethylphosphate (triethylphosphite, phenol); diethylphosphatemorpholide (triethylphosphite, morpholine); monobutylphenylphosphonate (dibutylphenylphosphonate, water); monoethylphosphatemonodimethyl amide (diethylphosphatedimethylamide, water). As suitable starting materials, there are mentioned various polychlorocyclopentadienes and -cyclopentenes, as well as hexabromocyclopentadiene, tetrachlorodifluorocyclopentadiene, pentachloromonofluorocyclopentadiene, hexachlorodifluorocyclopentene, hexachlorodibromocyclopentene and hexachlorodiiodocyclopentene.
