Additionally, it is used in the manufacturing of adhesives, coatings, and inks. Exposure to 4-Vinyl-1-cyclohexene can cause irritation to the skin, eyes, and respiratory tract, so proper handling and safety precautions are necessary when working with this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 100-40-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100-40:
13 % 10 = 3
So 100-40-3 is a valid CAS Registry Number.

Precursor effect on the property and catalytic behavior of Fe-TS-1 in butadiene epoxidation

Wu, Mei,Zhao, Huahua,Yang, Jian,Zhao, Jun,Song, Huanling,Chou, Lingjun

, p. 2103 - 2109 (2017)

The effect of iron precursor on the property and catalytic behavior of iron modified titanium silicalite molecular sieve (Fe-TS-1) catalysts in butadiene selective epoxidation has been studied. Three Fe-TS-1 catalysts were prepared, using iron nitrate, iron chloride and iron sulfate as precursors, which played an important role in adjusting the textural properties and chemical states of TS-1. Of the prepared Fe-TS-1 catalysts, those modified by iron nitrate (FN-TS-1) exhibited a significant enhanced performance in butadiene selective epoxidation compared to those derived from iron sulfate (FS-TS-1) or iron chloride (FC-TS-1) precursors. To obtain a deep understanding of their structure-performance relationship, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Temperature programmed desorption of NH3 (NH3-TPD), Diffuse reflectance UV–Vis spectra (DR UV–Vis), Fourier transformed infrared spectra (FT-IR) and thermal gravimetric analysis (TGA) were conducted to characterize Fe-TS-1 catalysts. Experimental results indicated that textural structures and acid sites of modified catalysts as well as the type of Fe species influenced by the precursors were all responsible for the activity and product distribution.

Nickel(0) and palladium(0) complexes with 1,3,5-triaza-7-phosphaadamantane. Catalysis of buta-1,3-diene oligomerization or telomerization in an aqueous biphasic system

The positive role of cadmium in TS-1 catalyst for butadiene epoxidation

Wu, Mei,Song, Huanling,Wang, Fang,Chou, Lingjun

, p. 207 - 212 (2013)

A series of Cd modified titanium silicalite 1 catalysts with different Cd content (xCd-TS-1, x = 1-15) were successfully prepared by ultrasound impregnation. Epoxidation of butadiene over these catalysts were investigated using hydrogen peroxide as oxidant, which indicated that Cd greatly improve the catalytic performance of TS-1 and the selectivity of epoxide. Various characterization methods including quantum chemical calculation were employed to explore the specific roles of Cd in promoting TS-1 catalytic activity. Theoretical calculation consistently suggested TiO bond were weakened owing to the introduction of Cd, which resulted in the structure of Cd-TS-1 becoming more relaxant. As a consequence, it is favorable to methanol solvent and H 2O2 interacting with the Ti active site to form five-member transition state during reaction. It was observed that catalysts modified with 1-5 wt% Cd presented both high catalytic activity and good reusability. The highest yield of 0.63 mol/L of vinyloxirane (VO) was obtained, while turnover number (TON, determined as the molar VO obtained per molar Ti atom) could reach to 1466.

Seed-mediated Growth of Alloyed Ag-Pd Shells toward Alkyne Semi-hydrogenation Reactions under Mild Conditions?

Zheng, Yuqin,Tan, Taixing,Wang, Cheng

, p. 3071 - 3078 (2021)

Ag@Ag-Pdx core-shell nanocomposites with various Ag/Pd ratio were deposited on Ag nanoplates using a seed growth method. When physically loaded on C3N4, Ag@Ag-Pd0.077/C3N4 with optimized Ag/Pd ratio could accomplish high catalytic performance for the semi-hydrogenation of phenylacetylene as well as other aliphatic (both terminal and internal alkynes) alkynes and phenylcycloalkynes containing functional groups (such as ester, hydroxyl, ethyl groups) under room temperature and 1 atm H2. The alloying and ensemble effects are used to interpret such catalytic performance.

Mechanistic Insight into High-Spin Iron(I)-Catalyzed Butadiene Dimerization

Lee, Heejun,Campbell, Michael G.,Hernández Sánchez, Raúl,B?rgel, Jonas,Raynaud, Jean,Parker, Sarah E.,Ritter, Tobias

, p. 2923 - 2929 (2016)

Iron complexes are commonly used in catalysis, but the identity of the active catalyst is often unknown, which prevents a detailed understanding of structure-reactivity relationships for catalyst design. Here we report the isolation and electronic structure determination of a well-defined, low-valent iron complex that is an active catalyst in the synthesis of cis,cis-1,5-cyclooctadiene (COD) from 1,3-butadiene. Spectroscopic and magnetic characterization establishes a high-spin Fe(I) center, which is supported by DFT studies, where partial metal-ligand antibonding orbital population is proposed to allow for facile ligand exchange during catalysis.

?-Arene Complexes of Nickel(II). Synthesis (from Metal Atoms) of (?-Arene)bis(pentafluorophenyl)nickel(II). Properties, ?-Arene Lability, and Chemistry

Gastinger, Robert G.,Anderson, Bruce B.,Klabunde, Kenneth J.

, p. 4959 - 4966 (1980)

A new series of transition-metal-?-arene complexes has been prepared by a metal atom synthetic method.The deposition of Ni vapor, C6F5Br, and arenes has prodused high yields of (C6F5)2Ni-?-arene complexes.A variety of ?-arene ligands are η6 bound by the (C6F5)2Ni moiety, resulting in soluble highly labile materials, where the ?-arene ligand is exchangeble at room temperature.These complexes have not been isolable when ?-bonding ligands other then C6F5 have been employed.The formation of the ?-toluene complex proceeds through a pseudostable C6F5NiBr species that can be trapped at -80 deg C with R3P but decomposes by reductive elimination of CF5-CF5 in the absence of R3P or electron-rich arenes.It is likely that C6F5NiBr-?-arene is formed initially, which then disproportionates to (C6F5)2Ni-?-arene and NiBr2.Due to the high lability of the ?-arene ligand, these complexes possess a rich chemistry.Displacement of the ?-arene ligand can bee carried out cleanly and in high yield by P(Et)3, 1,5-cyclooctadiene, and THF to form (C6F5)2NiL2.Treatment of (?-toluene)bis(pentafluorophenyl)nickel (1) with norbornadiene at 0 deg C causes the formation of a high polymer of norbornadiene as well as (?-norbornadiene)bis(pentafluorophenyl)nickel, which appears to be either the active polymerization catalyst or its precursor.Similarly, treatment of 1 with 1,3-butadiene at 25 deg C and 1 atm causes the formation of new organometallic compound and the production of cyclic tetramers of 1,3-butadiene.When 1 was treated with cyclopentadiene at 0 deg C, a rapid production of C6F5H was observed with the subsequent formation of a dimeric nickel complex (C6F5)2(Cp)2Ni2(C5H6) where the Ni atoms appear to be bound together through a mutually ?-bonded cyclopentadiene (C5H6) ligand.Reductive elimination reactions have also been induced under mild conditions by addition of CO or C2H4.With CO a nearly quantitative production of C6F5C6F5 and Ni(CO)4 took place.Lastly, 1 served as a short-lived arene hydrogenation catalyst at room temperature.
