| titleOfInvention | Manufacture of organic compounds containing halogen and phosphorus |
| abstract | The invention comprises compounds of formula <FORM:0747824/IV(a)/1> where R1 and R2 are alkyl or halogen-alkyl groups, X and Y are -NH-, >NR2 or >NR1, R1 and R2 being as above, Z is O or S, R4 is H, halogen or as R1, R5 is H, an alkyl or halogen-alkyl group, an aryl residue or -OR1, SR1, NH2, -NHR1 or -NR1R1, R1 being as above. These compounds may be made by reacting a compound of formula <FORM:0747824/IV(a)/2> where R1, R2, X, Y and Z are as above and R3 is as R1, with a compound of formula <FORM:0747824/IV(a)/3> where R4 and R5 are as above to split out a compound of formula Hal-R3. Representative of values specified for R1, R2 and R3 are methyl, isopropyl, 2-butyl-octyl, octadecyl and 2-chlorethyl groups. Representative of specified carbonyl compounds used as startingmaterial are dichloracetaldehyde, bromal, chloral, 1,1-dichlor-, 1,1,3-trichlor-, 1,1,3,3-tetrachlor-, pentachlor- and hexachlor-acetone, o -trichlor-, 4-chloro-o -trichlor- and 4-methyl-o -trichlor-acetophenone, ethyl trichloracetate and trichlorthioacetate and trichloracetic acid dimethylamide. The reactants react in equimolecular proportions irrespective of the quantities present. Inert solvents, e.g. benzene and dioxane may be present. Advantageously the reaction is finished by heating to 50-120 DEG C. The compounds are penticides. In examples: (1) chloral is reacted with [(C2H5)2N]2 POC2H5 in benzene solution and with initial cooling to yield [(C2H5)2N]2POCCl2.CHO, it bein stated that 1,1,3,3-tetrachloracetone may be used instead of chloral and in (2) ethyl trichloracetate is added to [(C2H5)2N]2 POC2H5 in benzene solution as in (1) to yield [(C2H5)2N]2 POCCl2COOC2H5. |
