Conclusions N-(3-Trialkylsilylpropyl)formamides (II) and N,N-bis(3-trialkylsilylpropyl)thioureas (III), together with a small amount of the trialkyl-(3-isothiocyanatopropyl)silane, are formed when trialkyl-(3-aminopropyl)silanes are reacted with formaldehyde and sulfur in aqueous-ethanol medium. 1,3,5-Tris(trialkylsilylpropyl)hexahydrotriazines are the intermediate products in these reactions.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 666–668, March, 1977. 相似文献

The fusion of 3,8-diphenyl-, 1,2-diphenyl-, and 6-methyl-2,7-diphenyl-indolizines with sulfur results in the formation of bis(indolizin-3-yl) disulfides with the respective substituents. Bis(2,8-diphenylindolizin-3-yl) disulfide is reduced to the original indolizine, and its treatment with nitric acid gives 2,8-diphenyl-1, 3-dinitroindolizine. Bis(dibenzo[b,g]indolizin-11-yl) disulfide is obtained from dibenzo[b,g]indolizine. The formation of the disulfides is apparently a general region of indolizines without substituents at C3 or C1 of the pyrrole ring. The structures of the disulfides obtained have been confirmed by data from x-ray diffraction analysis and NMR spectroscopy.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1371–1375, October, 1984. 相似文献

Conclusions The following reactions were effected in the presence of the coordination initiators Fe(CO)5 + i-C3H7OH (or Hexametapol): a) Telomerization of vinyl chloride with 1,1,1-trichloropropane and 1,1,1,3,3-pentachloropropane. Telomers that contain 1–3 monomeric units in the molecule were isolated, b) The addition of 1,1,1,3-tetrachloropropane and 1,1,1-trichloroethane to isobutylene; the adducts were obtained in good yields, c) The reaction of allyl chloride with 1,1,1,3-tetrachloropropane, which leads to the formation of the adduct and by-products as the result of the partial fragmentation of the ClCH2CH2CCl2CH2CHCH2Cl radicals with the cleavage of chlorine atom.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 174–177, January, 1977. 相似文献

We have recently reported a novel rearrangement reaction involving an intramolecular metathesis between M-M and Fe-Fe bonds in the dinuclear iron complexes (Me2MMMe2)[η5-C5R4)Fe(CO)]2(μ-CO)2 (M=Si, Ge; R=H, Me):[1-5].In order to extend the applied range of the rearrangement reaction we tried to synthesize the digermyl briged diruthenium analogues. The results showed a great difference between them. 相似文献

The reaction of Fe3(CO)12 with O,O′‐dialkyldithiophosphate diethylamine salts (RO)2P{S}SH · Et2NH (R = CH3, CH2CH3) resulted in the formation of trinuclear cluster complex {μ‐SP(OR)2Fe[S2P(OR)2)]S‐μ]}Fe2(CO)6 [R = CH3 ( 1 ), CH2CH3 ( 2 )]. The two complexes were characterized by elemental analysis, FT‐IR, NMR (1H, 31P and 13C) spectroscopy, as well as by X‐ray diffraction analyses. Crystal structures reveal that one P–S bond is cleaved during the reaction, yielding the [2Fe2S] unit together with FePS3(CO)2. The other dialkyldithiophosphate coordinated with iron by S, S chelating model. The trinuclear cluster was observed with the P‐Fe and S–Fe bond formed by the P‐S activation. In addition, the electrochemical properties for complex 2 as an illustration was also studied by cyclic voltammetry in MeCN. 相似文献

The photochemistry of Fe(CO)5 (5) has been studied in heptane, supercritical (sc) Ar, scXe, and scCH4 using time-resolved infrared spectroscopy (TRIR). 3Fe(CO)4 ((3)4) and Fe(CO)3(solvent) (3) are formed as primary photoproducts within the first few picoseconds. Complex 3 is formed via a single-photon process. In heptane, scCH4, and scXe, (3)4 decays to form (1)4 x L (L = heptane, CH4, or Xe) as well as reacting with 5 to form Fe2(CO)9. In heptane, 3 reacts with CO to form (1)4 x L. The conversion of (3)4 to (1)4 x L has been monitored directly for the first time (L = heptane, kobs = 7.8(+/- 0.3) x 10(7) s(-1); scCH4, 5(+/- 1) x 10(6) s(-1); scXe, 2.1(+/- 0.1) x 10(7) s(-1)). In scAr, (3)4 and 3 react with CO to form 5 and (3)4, respectively. We have determined the rate constant (kCO = 1.2 x 10(7) dm3 mol(-1) s(-1)) for the reaction of (3)4 with CO in scAr, and this is very similar to the value obtained previously in the gas phase. Doping the scAr with either Xe or CH4 resulted in (3)4 reacting with Xe or CH4 to form (1)4 x Xe or (1)4 x CH4. The relative yield, [(3)4]:[3] decreases in the order heptane > scXe > scCH4 > scAr, and pressure-dependent measurements in scAr and scCH4 indicate an influence of the solvent density on this ratio. 相似文献

The determination of precise, low-temperature crystal structures of [Fe3(CO)12] has shown that, on decreasing the temperature, the bridging ligands become progressively more symmetric, the bridged FeFe bond shortens and the atomic displacement parameters show a congruent behaviour with temperature. 相似文献

The reaction of PhCN with Ru3 (CO)12 in the presence of acetic acid gives H4Ru4(CO)12, (I), (μ-H)Ru3(CO)10(μ-NCHPh) (II) and (μ-H)Ru3(CO)10(μ-NH-CH2Ph) (III) as the main products. Reaction under 110 atm of H2 gives more III and also gives benzylamine. Replacement of acetic acid by H2 at atmospheric pressure gives only II. When H4Ru4CO)12 reacts with PhCN alone or in the presence of NaOH, II is formed as the only product.The structures of II and III have been fully elucidated by X-ray methods. The nitrogen atom of the NCHPh ligand in II and that of the NHCH2Ph ligand in III, interact with the isosceles-triangular metal cluster, symmetrically bridging the shortest Ru(1)-Ru(2) edge. A hydride ligand in both II and III bridges the same Ru(1)-Ru(2) edge of the cluster. Under mild conditions acetic acid is an essential requirement for the activation of Ru3(CO)12 for reaction with PhCN to give III, which cannot be obtained under these conditions from II. 相似文献
