Treatment of C2-symmetric chiral acetylenes, prepared from (R)-1,1â²-bi-2-naphthol, with dichlorobis(trialkylphosphine)-platinum or -palladium in the presence of a CuI catalyst in amine gave high molecular-weight polynuclear complexes, which show a large negative optical rotation.
在胺中使用 CuI 催化剂,用二氯双(三烷基膦)铂或钯处理由 (R)-1,1â²-双-2-萘酚制备的 C2 对称手性乙炔,可得到高分子量的多核络合物,这些络合物显示出很大的负旋光性。
