Definitions
- the present invention relates to new palladaphosphacyclobutanes and a process for their preparation.
- Palladaphosphacyclobutanes play an important role as catalysts for a number of processes. Examples of such processes are the synthesis of substituted styrenes, stilbenes and cinnamic acids from aryl halides.
- Clark describes in Inorg. Chim. Acta 31, (1978), L441 -L442 the reaction of PdCI 2 (NCPh) 2 with two equivalents of P (t-Bu) 3 to the corresponding palladaphosphacyclobutane in 70% yield.
- the toxicologically questionable solvent methylene chloride is used, in which both the starting material and the product are soluble.
- the solvent is removed, the product is extracted with benzene and then precipitated by adding hexane.
- the process is ecologically and economically disadvantageous due to the use of two equivalents of P (t-Bu) 3 per equivalent of palladium and the use of methylene chloride and benzene.
- Clark describes in Inorg. Chim. Acta 31, (1978), L441 -L442 the reaction of K 2 PdCI 4 with two equivalents of P (t-Bu) 3 to the corresponding palladaphosphacyclobutane in 72% yield. Dimethylformamide is used as the solvent in this process. To isolate this palladaphosphacyclobutane, the solvent is removed and the product is precipitated by adding ethanol. Clark describes an analogous process in Organometallics 1, (1982), 658-666 in which Na 2 PdCI 4 and three equivalents of P (t-Bu) 3 are used as starting materials and the corresponding palladaphosphacyclobutane is obtained in a yield of 75%. Both methods are based on the use of two or three equivalents of P (t-Bu) 3 pro Equivalent palladium ecologically and economically disadvantageous.
- Clark describes in Inorg. Chem. 18, (1979), 2803-2808 the reaction of PdCI 2 (NCPh) 2 with one equivalent of P (t-Bu) 3 to the corresponding palladaphosphacyclobutane without indication of the yield.
- the toxicologically questionable solvent methylene chloride is used in which both the starting material and the product are soluble.
- the solvent is removed, the product is extracted with benzene and then precipitated by adding hexane.
- the process is ecologically and economically disadvantageous due to the use of methylene chloride and benzene.
- the invention relates to palladaphosphacyclobutanes of the formula (I)
- R 1 , R 2 independently of one another are hydrogen, (C 1 -C 4 ) -alkyl, (C 3 -
- R, R 4 , R 5 , R 6 independently of one another (C r C 8 ) alkyl, (C 3 -C 12 ) cycloalkyl, or aryl; or wherein R 1 and R 2 , R 1 or R 2 and R 3 or R 4 , R 3 and R 4 , R 3 or R 4 and R 5 or R 6 , or R 5 and R 6 together form an aliphatic ring with 4 form up to 10 carbon atoms;
- R 5 and R 6 , R 3 or R 4 and R 5 or R 6 together form an aromatic ring having 5 to 9 carbon atoms;
- Y represents an anion of an inorganic or organic acid
- R 1 , R 2 are independently phenyl
- R 5 , R 6 independently of one another are phenyl, naphthyl or anthracenyl, which can be substituted by 1 to 3 (C r C 4 ) -alkyl or 1 to 3 (C r C 4 ) -alkoxy groups.
- Palladaphosphacyclobutanes of the formula (I) are particularly preferred in which R 3 , R 4 independently of one another are phenyl, R 5 , R 6 independently of one another o-trifluoromethylphenyl, o-
- Trifluoromethyl-p-tolyl o-trifluoromethyl-p-methoxy-phenyl, o-methoxy-phenyl, o, p-dimethoxy-phenyl, o, o, p-trimethoxy-phenyl, tert-butyl, n-butyl, isopropyl , Isobutyl, cyclohexyl, 1 - methylcyclohexyl.
- the palladaphosphacyclobutanes according to the invention represent a new class of catalysts. Their catalytic activity in the olefination of aryl halides is exceptional compared to the prior art, so that there is great technical interest in the compounds according to the invention.
- the invention further relates to a process for the preparation of compounds of the formula 1, characterized in that a phosphane of the formula (II)
- R 1 to R 6 have the meanings mentioned above and R 7 is hydrogen or deuterium, with a palladium salt of the formula (IM), a palladium complex of the formula (IV) or an alkali metal palletate of the formula (V)
- M is sodium, potassium or lithium and L is 1, 5-cyclooctadiene, acetonitrile or benzonitrile, in the presence of an organic solvent.
- the phosphane of the formula (II) and the palladium compound of the formula (III), (IV) or (V) are in a molar ratio of phosphine to Pd compound of 0.1 to 20, in particular 0.1 5 to 15, preferably 0.2 to 10, particularly preferably from 0.8 to 1.2.
- Aliphatic hydrocarbons and aromatic hydrocarbons are suitable as solvents. Toluene or xylenes are very suitable.
