| 摘 要： | 本文用自旋捕捉技术和ESR方法,对亚磷酸二烷基酯(RO)2P(O)H(R=C2H5,n-C3H7,i-C3H7,n-C4H9)及其汞化物(RO)2 P(O)HgX(X=OAc,Cl,Br)的光解产物进行了研究。结果表明,亚磷酸二烷基酯的汞化物比亚磷酸二烷基酯更容易产生自由基(RO)2p(O)。据此对汞化物中P-Hg的成键特征进行了讨论。

| Abstract: | The active intermediates produced in the photolysis of dialkyl phosphites (RO)_2P(0)H (R = C_2H_5, n-C_3H_7, i-C_3H_7, n-C_4H_8) and their mercury derivatives(RO)_2P(0)HgX(X = OAc, Cl, Br)were studied by spin trapping and ESR spectro-scopy. The results showed that radicals (R0)_2 P(0) were formed from the above two types of compounds during UV irradiation, and could be trapped by PBN. From the fact that the homolysis of P-Hg bond is much easier than that of P-H bond, the bonding characteristics of P-Hg bond in the mercury compounds is discussed. |
