Process for the coupling ofn a) nucleophiles selected from the group alcohols, thioles, amines, metallised hydrocarbons,nCH-acidic compounds and metal cyanides, or of b) carbon monoxide mixed with water, alcohols, ammonia, primary or secondary amines,nto organic compounds selected from the group of leaving-group-containing aromatics,nhetero-aromatics with a C-bonded leaving group, aromatic or hetero-aromatic methylncompounds with a leaving group bonded to the methyl group, ethylenically unsaturatednorganic compounds with a C-bonded leaving group, or organic allyl compounds with anleaving group in allyl position, or c) vinyl compounds with leaving-group-containing aromatics, nwhilst cleaving the leaving group in the presence of Pd complexes with monophospholinenligands as the catalyst, whereby variants b) and c) are carried out in the presence of anninorganic base or organic nitrogen base, the process being characterised in that the Pdncomplex contains secondary monophosphines with aliphatic, branched or cyclic substituentsnas ligands. |
