  • Patent number: 11447462
    Abstract: The present invention describes a new alkynylation and cyanation agent, as well as its preparation and use to introduce nitrile (cyano) or alkyne groups into chemical target molecules by means of an electrophilic reaction. To enable an electrophilic reaction, the chemical backbone of dibenzothiophene was used.
    Type: Grant

  • Patent number: 9962690
    Abstract: The present invention deals with the synthesis and applications of new cationic compounds being useful as metal ligands. Specifically, N-alkyl/aryl substituted pyridiniophosphines are prepared and used as ligands for transition metals. The so-obtained metal complexes and their use as catalysts in chemical synthesis is also described. It also worth mentioning that N-alkyl/aryl pyridiniophosphines can be synthesized through a short, scalable and highly modular route.

  • Patent number: 8981126
    Abstract: Phosphenium compounds with the general formula I: in which R1, R2, R3 and R4 are identical or different and represent a linear or branched C1-C6-alkyl radical, which can optionally be substituted, or R1 and R2 and/or R3 and R4 are bonded to one another with the formation of a ring, R5 and R6 stand for a saturated or unsaturated and linear or branched alkyl group, alkenyl group or aryl group, which can have suitable substituents, even heteroatoms as substituents, or a heteroatom-comprising hydrocarbon group, which can have suitable substituents, and the R5 and R6 radicals can form a ring which can be 4- to 20-membered, saturated or unsaturated and alicyclic or heteroalicyclic and can exhibit suitable substituents, X? represents an anion, a process for the preparation thereof, and also the use of these compounds in metal complexes which can be used as catalysts in organic synthesis, are claimed.
