Claim:
Process for preparing a Palladium(0) compound, comprising reaction of a palladium compound with one or more compounds of the general formula I in the presence of a base: in which: each A is independently a CR 7 R 8 -radical where one of the A radicals may be oxygen, sulphur, an NR 9 group or an SiR 10 R 11 group, or where the A radicals may be a constituent of a 5- to 20-membered ring system, x is an integer from 2 to 4, and each R 1 to R 11 is independently selected from R, OR, halogen, CN, NO 2 , NR 2 , C(O)R, C(O)OR, OC(O)R, CONR 2 , NHCO 2 R, NHCOR, CH═CH—CO 2 R, Si(R) 3 , Si(OR) 3 , SiR(OR) 2 , SiR 2 (OR), SO 3 R, SO 2 R, SOR, SR, PR 2 , POR 2 , PO 3 H, PO(OR) 2 , in which R is a hydrogen atom, a substituted or unsubstituted C 1-10 -alkyl radical, a substituted or unsubstituted, mono- or polyunsaturated C 1-10 -alkenyl radical, or a substituted or unsubstituted, optionally heteroatom-containing C 5-10 -aryl radical, and the substituents on the alkyl radical or the alkenyl radical are selected from halogen, O—C 1-10 -alkyl, phenyl, O-phenyl, OH, NH 2 and halogenated C 1-10 -alkyl, and the substituents on the aryl radical are selected from halogen, C 1-10 -alkyl, O—C 1-10 -alkyl, phenyl, O-phenyl, OH, NH 2 and halogenated C 1-10 -alkyl, where R 2 and R 3 and/or R 5 and R 6 together with the carbon atoms bonded thereto may be a constituent of a 5- to 7-membered, optionally heteroatom-containing ring.
