| titleOfInvention | Halogenated derivatives of pyridine |
| abstract | A functional or hydraulic fluid comprises a compound of the general formula <FORM:1106916/C4-C5/1> where A is an oxygen or sulphur atom, X, Y, R and R1 are each fluorine, chlorine or bromine, m and n are integers and have values from 0 to 5, and the sum of m and n is from 0 to 5, a and b are integers and have values from 0 to 2 and the sum of a and b is from 0 to 2, provided the sum a+b+m+n is from 1 to 7. Conventional additives may be added to the fluids. Compounds prepared in the examples are 3-(21-, 31-, and 41-bromophenoxy) pyridine, 3-(31-fluorophenoxy) pyridine, 3-(41-chlorophenylmercapto)-5-chloropyridine, 3-(21, 41-dibromophenoxy)-5-chloropyridine, 3-(31-chlorophenoxy)-5-chloropyridine and 3-(21,31,41,51, 61-pentachloro-phenoxy) pyridine; many other such compounds are specified.ALSO:The invention comprises compounds of the general formula <FORM:1106916/C2/1> where A is oxygen or sulphur, X, Y, R and R1 are each fluorine, chlorine, or bromine, m and n are integers of 0 to 5 and the sum of m and n is from 0 to 5, a and b are integers of 0 to 2 and the sum of a and b is from 0 to 2, provided that the sum a + b + m + n is from 1 to 7. They may be obtained (A) by reacting an alkali metal salt of a phenol or thiophenyl of the general formula <FORM:1106916/C2/2> wherein Me is an alkali metal with a pyridine compound of the formula <FORM:1106916/C2/3> where Hal is a halogen atom, or (B) by reacting an alkali metal substituted 3-hydroxy- or mercapto-pyridine of the formula <FORM:1106916/C2/4> with a halogenated benzene of the formula <FORM:1106916/C2/5> Either reaction may be effected in an inert solvent preferably at 100 DEG to 250 DEG C. and preferably in the presence of, as catalyst, cuprous ion or a source of cuprous ion, and, as co-catalyst, potassium iodide or other source of iodine ion. Compounds prepared in the examples are 3-(21-, 31- and 41-bromophenoxy) pyridine, 3-(31-fluoro-phenoxy) pyridine, 3-(41-chlorphenylmercapto)-5-chloropyridine, 3-(21,41-dibromophenoxy)-5-chloropyridine, 3 - (31 - chlorophenoxy) - 5-chloropyridine and 3 - (21,31,41,51, 61 - pentachlorophenoxy) pyridine; many other compounds are specified. |
