摘要

具有两种路易斯碱原子[As(III)和S(II)]的As(III)硫酸盐对重金属盐的配位能力几乎没有研究。我们发现As(SPh)3 (A)、Me-As(SPh)2 (B)和2- o2n - phs -As(SPh)2 (C)与醋酸盐M(OAc)2 (M = Cd, Pb, Hg)反应生成金属硫代苯酚M(SPh)2 (B和Cd(OAc)2反应生成ph -Cd-OAc·Cd(SPh)2)，与HgCl2反应生成(ph -Hg- cl)2·HgCl2除外)。镉和铅(II)的噻吩酸酯对相应的乙酸酯和氯化物无反应，而Hg(SPh)2产生ph -Hg- oac和(PhS-Hg-Cl)2·HgCl2。提出了这些反应的可能机制。

The instability of coordinated As(III) thiolates, As(SPh)3 and R-As(SPh)2 (R = Me, 2-nitrophenyl), to heavy metal cations

The coordination ability of As(III) thiolates, having two kinds of Lewis base atoms [As(III) and S(II)], towards heavy metal salts was virtually not studied. We have found that As(SPh)3 (A), Me-As(SPh)2 (B), and 2-O2N-PhS-As(SPh)2 (C) with the acetates M(OAc)2 (M = Cd, Pb, Hg) gave the metal thiophenolate M(SPh)2 (except in the case of B and Cd(OAc)2 which gave PhS-Cd-OAc·Cd(SPh)2) and with HgCl2 gave (PhS-Hg-Cl)2·HgCl2. The thiophenolates of cadmium and lead(II) were not reactive towards their corresponding acetates and chlorides, while Hg(SPh)2 gave PhS-Hg-OAc and (PhS-Hg-Cl)2·HgCl2. Likely mechanisms for these reactions are suggested.

期刊介绍： Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
