A number of trioxorhenium(VII) compounds of the type ReO3X (X = NPri2, OMe, OBut, or O2CR; R = Me, CF3, But, or Ph) have been prepared from ReO3Cl, ReO3(OSiMe3), and Re2O7. The compounds form adducts with tetrahydrofuran, pyridine (py), 2-hydroxypyridine, and NNN′N′-tetramethylethylenediamine (tmen); examples are ReO3(OMe)(tmen) and ReO3(O2CMe)(py). For the carboxylates, the RCO2 group may be unidentate
许多trioxorhenium(的VII REO的类型)化合物3 X(X = NPR我2,青梅,OBU吨或O 2 CR; R = Me中,CF 3,卜吨,或pH)已经从REO制备3 Cl,ReO 3(OSiMe 3)和Re 2 O 7。化合物形成用四氢呋喃,吡啶(PY),2-羟基吡啶,并加合物NNN ' ñ 'N'-四甲基乙二胺(TMEN); 例如ReO 3(OMe)(tmen)和ReO 3(O 2 CMe)(py)。对于羧酸盐,RCO2个基团可以是不相同的或螯合的,这取决于另外的配体的性质。乙酰三氧氧配合物与苯甲酸发生交换反应,得到相应的苯甲酸酯。还描述了具有三甲基甲硅烷基酰胺,-酰亚胺和-氧化物基团Re [N(SiMe 3) 2 ](NSiMe 3) 2(OSiMe 3) 2的五坐标rh( VII)配合物,Ir和给出了nmr( 1 H, 13 C)数据。
