| titleOfInvention | Method for producing phosphabenzene compounds |
| abstract | A process for the preparation of phosphabenzene compounds of the formulae I and IIwhere R1 to R6, independently of one another, are hydrogen, COOM SO3M, NR3X, NR2, OR, COOR or SR, where M is hydrogen, NH4 or an alkali metal, X is an anion, R is hydrogen, C1-6-alkyl, or C1-12-alkyl, C6-12-aryl, C7-12-aralkyl or C3-6-heterocycloalkyl having 1 to 3 heteroatoms which may be substituted by the above radicals or linked to form fused rings, and-W- is a bridge comprising a covalent bond, an oxo group, a sulfur group, an amino group, a di-C1-6-alkylsilicon group or a C1-16-radial, which may be part of one or more linked cyclic or aromatic rings and may be interrupted by 1 to 3 heteroatoms, where the phosphabenzene ring o- or m-position not bonded to the bridge may carry one of the radicals R1 to R6,with the exception of bis-3,3'-(2,4,6-triphenyl-3-phosphabenzene)-1,1-biphenyl, by reacting corresponding pyrilium salts with PH3 in the presence of a catalytic amount of acid and in the presence or absence of a solvent or diluent, where the pyrilium salts are mixed with PH3 at above 0° C. and reacted at from 0° C. to 200° C. and at a pressure greater than 1 bar. |
