The syntheses of cis-bis(phenyl)platinum(II) compounds with substituents of increasing Van der Waals volumes in the ortho-positions of the phenyl rings are reported. The existence of E,Z-atropisomers with respect to the torsion about the platinumcarbon σ-bonds in these compounds is demonstrated NMR-spectroscopically. the E,Z-diastereoisomers of bis(2-t-butoxymethyl-6-methyl-phenyl)[P,P′-η2-1,2-bi
报道了在苯环的邻位具有增加的范德华体积的取代基的顺式-双(苯基)铂(II)化合物的合成。用NMR光谱法证实了这些化合物中E,Z-阻转异构体相对于关于铂is碳σ键的扭转的存在。的E,Z双(2-叔丁氧基甲基-6-甲基-苯基)[的-diastereoisomers P,P' -η 2 -1,2-双(二苯基膦基)乙烷]铂(II)已被分离并隔绝在制备规模。
