测定了33个三环己基脂肪族和芳香族羧酸锡在非配位溶剂(CDCl_3)中的~(13)C和~(119)Sn NMR谱。结果表明:化学位移δ(~(119)Sn)值主要由锡原子的配位数决定,结构上微小的变化。都能在δ(~(119)Sn)值上明显地表现出来。讨论了不同类型化合物间NMR参数间的关系。
The ~ (13) C and ~ (119) Sn NMR spectra of 33 tricyclohexyl aliphatic and aromatic tin carboxylates in a noncoordinating solvent (CDCl 3) were determined. The results show that the chemical shift δ (~ (119) Sn) value is mainly determined by the coordination number of tin atoms, and the structure is slightly changed. Both of them can be obviously expressed in δ (~ (119) Sn). The relationship between NMR parameters of different types of compounds is discussed.
