A novel bidentate catalytic ligand of general formula (I) is described. R represents a hydrocarbyl aromatic structure having at least one aromatic ring to which Q 1 and Q 2 are each linked, via the respective linking group, if present, on available adjacent atoms of the at least one aromatic ring. The groups X 3 and X 4 represent radicals joined via tertiary carbon atoms to the respective atom Q 1 and the groups X 1 and X 2 represent radicals joined via primary, or substituted aromatic ring carbon atom(s) to the respective atom Q 2. A and B represent an optional lower alkylene linking group. Q 1 and Q 2 each represent phosphorus, arsenic or antimony. A process for the carbonylation of ethylenically unsaturated compounds comprising reacting the compound with carbon monoxide in the presence of a source of hydroxyl groups, optionally, a source of anions and catalyst system obtainable by combining a metal of Group 8, 9 or 10 or a compound thereof and the bidentate ligand of general formula (I) is also described.
描述了一种一般式(I)的新型双齿催化配体。其中,R代表至少具有一个芳香环的烃基芳香结构,其中Q1和Q2分别通过至少一个芳香环上可用的相邻原子的相应连接基(如果存在)连接。基团X3和X4代表通过第三级碳原子连接到相应原子Q1的基团,基团X1和X2代表通过主要或取代的芳香环碳原子连接到相应原子Q2的基团。A和B代表可选的较低烷基连接基。Q1和Q2分别代表磷、砷或锑。还描述了一种用于乙烯基不饱和化合物的羰基化的方法,包括将该化合物与一氧化碳在羟基源的存在下反应,可选地,与阴离子源和由结合第8、9或10族金属或其化合物以及一般式(I)的双齿配体的催化系统获得的催化剂。
