SYNTHESIS AND X-RAY CRYSTALLOGRAPHY OF CHIRAL TROPOCORONANDS
摘要:
The synthesis of several chiral tropocoronands (6 and 7) has been accomplished. These compounds have been shown to complex with various metals. Tropocoronands that have been synthesized include H-2(TC-3,cyhex) through H2(TC-G,cyhex) (6) and H-2(TC-3,diphen) through H-2(TC-6,diphen) (7). The route is short and the tropocoronands are easily purified by chromatography or recrystallization. Two other groups have been incorporated into tropocoronands, H-2(TC-3,binap) (9) and H-2(TC-6,pent) (10).
rac‐Bisμ‐trans‐2,2′‐[pentane‐1,5‐diylbis(azanediyl)]ditroponato}dipalladium(II), [Pd2(C19H20N2O2)2], has been synthesized and fully characterized using single‐crystal X‐ray diffraction, 1H NMR, FT–IR and mass spectroscopy. The trans coordination, vaulted structure and anti conformation have been unequivocally established from the X‐ray diffraction studies. This is the first example of a bis(aminotroponato)palladium
rac -Bis μ-反式-2,2'-[戊烷-1,5-二基双(氮杂二基)]对苯二甲酸酯}二钯(II),[Pd 2(C 19 H 20 N 2 O 2)2 ]合成并使用单晶X射线衍射,1 H NMR,FT-IR和质谱进行了全面表征。该反式协调,拱形结构和防X射线衍射研究明确地确定了构象。这是双(氨基troponato)钯配合物的第一个例子。在结晶状态下,该分子具有双重对称性,每个分子单元经历分子间错位的tropone环π堆积,以提供以层状方式与人字形堆积基序对齐的异手性互穿二聚体。
