Joined at Pd: Novel palladium catalysts like 1, in which the planar‐chiral phosphine acts as a bridging ligand, have been developed. These dimetallic complexes are highly enantioselective catalysts in the hydroxycarbonylation of alkenes, a reaction that has proven problematic over the years. PTSA=para‐toluenesulfonic acid.
在Pd处加入:已开发出新型的
钯催化剂,如1,其中平面手性膦可作为桥连
配体。这些双
金属络合物是烯烃羟基羰基化反应中的高度对映选择性催化剂,多年来已证明该反应存在问题。
PTSA =
对甲苯磺酸。
