摘要:
研究了大环基质苯环中的邻甲基对上环具有磷酰胺桥的空配体化学的影响。邻甲基的存在可以防止 C 4v 对称性的磷空配体的形成,并有利于 C 2v 对称性大环系统的形成,增强磷空配体在有机溶剂中的溶解度,阻碍磷(III)空配体的氧化并降低磷(V)空配体,防止磷酰胺空配体的双核钼配合物的形成,并有利于其四核类似物的形成。

Effect of ortho-methyl groups in the benzene rings of the macrocyclic matrix on the chemistry of cavitands with phosphorous amide bridges in the upper rim is studied. The presence of ortho-methyl groups is shown to prevent formation of phosphacavitands of C 4v symmetry and favor formation of macrocyclic systems of C 2v symmetry, enhance solubility of phosphacavitands in organic solvents, hinder oxidation of phospha(III)cavitands and decrease the yield of phospha(V)cavitands, prevent formation of binuclear molybdenum complexes of phosphorous amide cavitands, and favor formation of their tetranuclear analogs.
