Process for preparing compounds by cross-coupling of enolizable carbonyl compounds, nitriles or their analogues with substituted aryl or heteroaryl compounds in the presence of a Brönsted base and of a catalyst or precatalyst containing a.) a transition metal, a complex, a salt or a compound of this transition metal from the group V, Mn, Fe, Co, Ni, Rh, Pd, Ir, Pt) and b.) at least one sulphonated phosphane ligand in a solvent or solvent mixture.
通过在存在Brönsted碱和包含a.)过渡金属、配合物、盐或来自V、Mn、Fe、Co、Ni、Rh、Pd、Ir、Pt组的该过渡金属化合物的催化剂或前催化剂的情况下,使用含有至少一种磺化膦配体的溶剂或溶剂混合物,通过交叉偶联烯醇化的羰基化合物、腈或它们的类似物与取代芳基或杂环芳基化合物的方法。
