Definitions
- the present invention relates to a process for the preparation of mono (fluoroalkyl) - or bis (fluoroalkyl) phosphoric acids, mono (fluoroalkyl) - or
- the tris (fluoroalkyl) difluorophosphoranes can be used as starting materials for the synthesis of various phosphates (WO 98/15562, DE 19641 138, EP 1 127 888) and a new tris (fluoroalkyl) trifluorophosphoric acid (DE 101 30 940) ,
- This acid can not only be used for the synthesis of various salts, but can also be hydrolyzed into the corresponding bis (fluoroalkyl) phosphinic acid (DE 102 169 97).
- Bis (fluoroalkyl) phosphine and fluoroalkyl phosphonic acid and their salts can also be obtained by hydrolysis of tris (fluoroalkyl) difluorophosphoranes (DE 102 169 95).
- a process known in the art for producing mono (perfluoroalkyl) and bis (perfluoroalkyl) fluorophosphanes is also a multi-step reaction based on the reaction between phosphorus and perfium alkyl halides, which are very expensive (T. Mahmood, JM Shreeve, Inorg. Chem., 25 (1986) 3128). This implementation often requires high pressures and temperatures.
- Trifluoromethylphosphorane is formed in the reaction of (CF 3 ) 2 Cd with PF 5 or PCI 5 (R. Eujen, R. Haiges, Z. Naturforsch., 53b (1998) 1455).
- Mono (pentafluorophenyl) - and bis (pentafluorophenyl) fluorophosphanes can be prepared in a multi-stage reaction in which the first step involves the reaction of pentafluorophenyl magnesium bromide with PCI 3 (M. Fild, O. Glemser, I. Hollenberg, Z. Naturforsch., 21b (1966) 920; DD Magnelly, G. Tesi, JU Löwe, WE McQuistion, Inorg. Chem., 5 (1966) 457; RMK Deng, KB Dillon, WS Sheldrick, J. Chem. Soc. Dalton Trans.
- Bis (pentafluorophenyl) chloro- or bromophosphine can be separated by means of fractional distillation and the corresponding fluorophosphoranes are formed by reaction with Cl 2 and subsequent reaction with AsF 3 or SbF 3 (M. Fiid, R. Schmutzier, J. Chem. Soc (A) 1969, 840).
- the object of the present invention is to provide a technical and economically advantageous process for the preparation of mono (fluoroalkyl) and bis (fluoroalkyl) phosphates and their corresponding phosphoranes, which in particular has good yields and is simpler and less expensive than that from the prior art Technique known.
- the invention is characterized in that bis (fluoroalkyl) phosphine or fluoroalkylphosphonic acid or its salts or derivatives by simple reaction with anhydrous hydrogen fluoride (HF) the corresponding fluoroalkylphosphoric acids with subsequent salt formation or directly the fluoroalkylphosphates in good yields form.
- HF hydrous hydrogen fluoride
- the mono (fluoroalkyl) - or bis (fluoroalkyl) phosphates can then subsequently be converted into the corresponding phosphoranes by treatment with strong electrophilic reagents or strong Lewis acids.
- Mono (fluoroalkyl) and bis (fluoroalkyl) phosphates in the context of the present invention are compounds in which the phosphorus bears five or four fluorine atoms in addition to one or two fluoroalkyl groups.
- the mono- and bis (fluoroalkyl) phosphates produced in accordance with the invention are therefore mono (fiuoraikyl) pentafluorophosphates and bis (fluoroalkyl) tetrafluorophosphates.
- the corresponding phosphoranes produced according to the invention accordingly contain four or three fluorine atoms which are directly connected to the phosphorus atom.
- fluoroalkyl groups for the purposes of the present invention straight-chain or branched alkyl or cycloalkyl groups which are fluorinated and which contain no, one, two or three double bonds.
- Fluorinated alkyl groups are, for example, difluoromethyl, trifluoromethyl, pentafluoroethyl, pentafluoropropyl, heptafluoropropyl, pentafluorobutyl,
- Perfluoroalkyl group means that all H atoms of the alkyl group are replaced by F atoms, as described above.
- the fluorinated alkyl groups may also contain one, two or three double bonds, for example correspondingly fluorinated allyl, 2- or 3-butenyl, isobutenyl, sec-butenyl, furthermore 4-pentenyl, isopentyl, hexenyl, heptenyl, octenyl, -CgHu, -C 10 H 19 to -C 20 H 39 .
- Fluorinated means that in a perfluoroalkyl or
- Perfluorocycloalkyl group 1 to 4 fluorine atoms are replaced by hydrogen atoms.
- Cycloalkyl groups are understood to mean, for example, saturated or partially or completely unsaturated cycloalkyl groups with 3-7 C atoms, such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclopentenyl, cyclopenta-1, 3-dienyl, cyclohexenyl, cyclohexa-1, 3-dienyl , Cyclohexa-1, 4-dienyl, phenyl, cycloheptenyl, cyclohepta-1, 3-dienyl, cyclohepta-1, 4-dienyl or cyclohepta-1, 5-dienyl, which are appropriately fluorinated and which have d- to C ⁇ -alkyl groups may be substituted, the cycloalkyl group and the cycloalkyl group substituted by C to C ⁇ -alkyl groups in turn being fluorinated.
- the process according to the invention for the production of mono- or bis (fluoroalkyl) phosphates and their corresponding phosphoranes thus comprises at least the reaction of a bis (fluoroalkyl) phosphinic acid or a (fluoroalkyl) phosphonic acid or a corresponding derivative of these acids with anhydrous hydrogen fluoride.
