Conclusions Derivatives of trichloromethylmercury RHgCCl3 (R=n-C3H7, cyclo-C6H11, C6H5CH2, and C6H5), which are stable in the absence of air, were obtained in almost quantitative yield by the reaction of the corresponding mercury tert-butoxides RHgOC(CH3)3 with chloroform at room temperature.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2803–2805, December, 1968. 相似文献

Thermal decomposition ranges of Cp2HfR, (R = Me, Ph) have been found by the DTA method. The thermal stability of hafnium derivatives greatly exceeds the stability of analogous titanium and zirconium compounds. Decomposition of Cp2HfR2 occurs by abstraction of σ-bonded groups which convert into RH. Hydrogen donors for the RH formation are both π-cyclopentadienyl and σ-bonded groups. The initial π-Cp2Hf structure rearranges to form the (η5-Cp)-(η5,η1-C5H4)Hf fragment. These react with HCl to produce Cp2HfCl2. It has been established that hydrogen exchange between cyclopentadienyl rings and methyl groups occurs during the thermal decomposition of Cp2HfMe2. As a result of the exchange process on thermal decomposition of Cp2HfMe2-d6, deuterium insertion into the cyclopentadienyl ring has been shown. The participation of solvent during the decomposition process of the hafnium derivatives has been studied. 相似文献

1. | Tris[tris(trimethylsilylmethyl)stannyl]- and tris[tris(trimethylsilylmethyl)germyl] thallium, the first stable compounds containing Sn-Tl and Ge-Tl bonds, have been prepared by the reaction of the hydrides of tris (trimethylsilylmethyl)tin and tris (trimethylsilylmethyl)germanium with triethylthallium. |
2. | The Sn-Tl bond is attacked in the reactions of the stannylthallium compound with lithium, mercury, oxygen, bromine, ethyl bromide, ethanol, and other reagents. |

Bis(triethylsilyl)mercury (I) and triethylsilyl(pentaethyldisilanyl)mercury (II) react with metallic sodium or potassium in benzene solution to give phenyltriethylsilane (III) and a mixture of III and 1-phenyl-2,2,3,3,3-pentaethyldisilane, respectively, instead of the expected silylmetallic compounds (e.g. Et3SiM and Et5Si2M, where M = Na or K). These results may be explained by the intermediate formation of silylmetallic compounds which reacted with the solvent. The reaction of I with potassium in toluene proceeds analogously. 相似文献

Metallic lithium and dibenzenechromium displace thallium from (Rf3Ge)3HgTl·1.5DME (Rf = C6F5, DME = 1,2-dimethoxyethane) to give (Rf3Ge)3HgLi·3DME and [(Rf3Ge)4Hg][Cr(C6H6)2]2, respectively. Reactions of thallium germylmercurate with halides of metals and organometallics in DME/EtOH solution produce ionic compounds of [(Rf3Ge)3Hg]? M+ type, which (depending on “M”) (a) may be isolated as pure compounds, (b) disproportionate, (c) form covalent derivatives Rf3Ge-m or (d) undergo alcoholysis. A general scheme for the reactions has been proposed. 相似文献
