    摘要: The invention relates to cyclopentadienylphosphazene complexes (CpPN complexes) of metals of the III. and VI. group and of the lanthanoids except for lutetium. The complexes of the invention are isolobal and isoelectric with respect to the [(CpSiN)TiR2] complexes. There is exactly one CpPN moiety in the complexes of the invention. The cyclopentadienyl moiety of CpPN represents a monodentate, anionic ligand of the metal atom in all complexes of the invention. The metal atom is also bound to other anionic ligands. In a preferred embodiment, both the cyclopenadienyl moiety and the nitrogen atom within CpPN bind to the metal atom so that CpPN represents a bidentate ligand. Complexes in which CpN represents a bidentate ligand are CpPN Constrained Geometry Complexes (CpPN-CGC). The invention also relates to methods for producing the complexes in situ. The CpPN complexes can be electrically neutral or be present as cationic complexes. Cationic complexes are formed when one of the other anionic ligands of the metal atom is replaced by a neutral ligand; counterions of the cationic CpPN complexes are preferably fluoroborate, tetraphenyl borate, tetrakis-(3,5-trifluormethylphenyl)borate. The complexes are produced in situ by reacting a metal halide with a protonated cyclopentadienylphosphazene CpPNH and an alkaline or alkaline earth salt of the desired other anionic ligand. The complexes according to the invention can be used as catalysts for the hydroamination and polymerization of polyolefins.

    摘要: A process is disclosed for producing α-chlor-methylen-triorganylphosphorane carboxylic acid derivatives having the formula (I), in which R stands for C organic substituents; A stands for CN or CO-B; B stands for C or O organic residues that remain inert in chlorinating conditions, by chlorinating phosphoranes having the formula (II) with chlorine. Chlorination is carried out in the presence of a mineral base as hydrogen chloride acceptor, whereas chlorine and the base are synchronously but separately introduced into the reaction mixture according to their consumption. The products (I) obtained by this process represent important intermediates for plant protective substances.
