Process for the coupling of
a) nucleophiles selected from the group alcohols, thioles, amines, metallised hydrocarbons, CH-acidic compounds and metal cyanides, or of
b) carbon monoxide mixed with water, alcohols, ammonia, primary or secondary amines, to organic compounds selected from the group of leaving-group-containing aromatics, hetero-aromatics with a C-bonded leaving group, aromatic or hetero-aromatic methyl compounds with a leaving group bonded to the methyl group, ethylenically unsaturated organic compounds with a C-bonded leaving group, or organic allyl compounds with a leaving group in allyl position, or
c) vinyl compounds with leaving-group-containing aromatics, whilst cleaving the leaving group in the presence of Pd complexes with monophospholine ligands as the catalyst, whereby variants b) and c) are carried out in the presence of an inorganic base or organic nitrogen base, the process being characterised in that the Pd complex contains secondary monophosphines with aliphatic, branched or cyclic substituents as ligands.
将a)亲核试剂(选择自羟基、硫醇、胺、金属化的碳氢化合物、CH-酸性化合物和金属氰化物中的一种)或b)与水、醇、氨、一级或二级胺混合的一氧化碳,与含有离去基团的芳香族化合物、带有C键合离去基团的杂环芳香族化合物、带有离去基团键合到甲基基团的芳香族或杂环芳香族甲基化合物、带有C键合离去基团的乙烯不饱和有机化合物,或带有离去基团的有机烯丙基化合物中的有机化合物耦合的过程,或c)含有离去基团的乙烯化合物,同时在Pd配合物存在下在单膦磷酮配体作为催化剂的情况下裂解离去基团,其中变体b)和c)在无机碱或有机氮碱存在下进行,所述过程的特征在于Pd配合物含有带有脂肪、支链或环状取代基的二级单膦磷酮作为配体。
