Solvent effect on the Raman spectra of mercury(II) halides: Solvent effect on the Raman spectra of mercury(II) halides. Sone, Kozo; Aritaki, Makiko; Hiraoka, Keiko; Fukuda, Yutaka (Fac. Sci., Ochanomizu Univ., Tokyo, Japan). Bull. Chem.In this article, certain chemicals are used. Some of their cas registry numbers are 592-04-1 and 143-36-2 Soc. Jpn., 49(7), 2015-16 (English) 1976. CODEN: BCSJA8. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 78 Raman spectra show that the Hg-X bond strengths in mercury(II) halides are remarkably weakened by the interaction with certain solvents. Relations between the degree of this weakening and (a) the Lewis basicity (Gutmann's donor no.) of the solvent and (b) the ionic character of the Hg-X bond are pointed out, together with a simple explanation. .

Reaction of borothallated carboranes with mercury(0) and sulfur: Reaction of borothallated carboranes with mercury(0) and sulfur. Bregadze, V. I.; Usyatinskii, A. Ya.; Godovikov, N. N. (Inst. Elementoorg. Soedin., Moscow, USSR). Izv. Akad. Nauk SSSR, Ser. Khim., (8), 1903-5 (Russian) 1983. CODEN: IASKA6. 592-04-1 and 67570-39-2 which are cas registry numbers of substances are two of reagents here. ISSN: 0002-3353. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) The title reaction proceeds with cleavage of the B-Tl bond. Thus, refluxing o-H2C2B10H9Tl(O2CCF3)2-9 with Hg in DMF 40 h gave o-H2C2B10H9HgO2CCF3-9 and bis(o-carboran-9-yl)mercury. .
