Check Digit Verification of cas no

The CAS Registry Mumber 3221-61-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,2 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3221-61:
52 % 10 = 2
So 3221-61-2 is a valid CAS Registry Number.

Chemical and Spectroscopic Studies on Copper Iodide Derived Organocuprates: New Insight into the Composition of Gilman's Reagent

Lipshutz, Bruce H.,Kozlowski, Joseph A.,Breneman, Curt M.

, p. 3197 - 3204 (1985)

Both 1H and 7Li NMR spectroscopy at high field have served to reveal that the addition of ethereal MeLi to MeCu/THF, in the absence of LiI, leads to unprecedented equilibria (Keq ca. 11) between Me2CuLi and MeLi plus Me3Cu2Li.From a series of spectra at -70 degC, a scheme is proposed to account for the signals observed in solutions of varying MeLi:MeCu ratios.These data lead to the conclusion that not only Gilman's reagent but also "Me3CuLi2" and "Me5Cu3Li2" are not discrete, but rather are composed of differing percentages of the same components.In the presence of LiI, or in Et2O solutions alone, however, this equilibrium does not exi sts for MeLi:MeCu ratios up to 1:1.Chemical tests on both ketones and esters, as well as a series of Gilman tests, fully corroborate the existence of various forms of Gilman's reagent.

Insight into decomposition of formic acid to syngas required for Rh-catalyzed hydroformylation of olefins

Liu, Lei,Chen, Xiao-Chao,Yang, Shu-Qing,Yao, Yin-Qing,Lu, Yong,Liu, Ye

, p. 406 - 415 (2020/12/07)

Formic acid (FA) is one kind of important bulk chemicals, which is recognized as a sustainable and eco-friendly energy carrier to transport H2 via dehydrogenation or CO via decarbonylation. Expectantly, FA upon decomposition into H2 and CO could be used as the syngas alternative for hydroformylation. In this paper, the behaviors of FA to release H2 as well as CO following the distinct pathways were carefully investigated for the first time, and then established a new hydroformylation protocol free of syngas. It was found that the atmospheric hydroformylation of olefins with formic acid (FA) as syngas alternative was smoothly fulfilled over Xantphos (L1) modified Rh-catalyst under mild conditions (80 °C, Rh concentration 1 mol %, 14 h), resulting in >90% conversion of the olefins along with the high selectivity to the target aldehydes (>93%). By using FA as syngas source, the side-reaction of olefin-hydrogenation was greatly depressed. The in situ FT-IR and the high-pressure 1H NMR spectroscopic analyses were applied to reveal how FA behaves dually as CO surrogate and hydrogen source over L1-Rh(acac)(CO)2 catalytic system, based on which the deeply insight into the catalytic mechanism of hydroformylation of olefins with FA as syngas alternative was offered.

Production of liquid hydrocarbon fuels with acetoin and platform molecules derived from lignocellulose

Zhu, Chenjie,Shen, Tao,Liu, Dong,Wu, Jinglan,Chen, Yong,Wang, Linfeng,Guo, Kai,Ying, Hanjie,Ouyang, Pingkai

supporting information, p. 2165 - 2174 (2016/04/19)

Acetoin, a novel C4 platform molecule derived from new ABE (acetoin-butanol-ethanol) type fermentation via metabolic engineering, was used for the first time as a bio-based building block for the production of liquid hydrocarbon fuels. A series of diesel or jet fuel range C9-C14 straight, branched, or cyclic alkanes were produced in excellent yields by means of C-C coupling followed by hydrodeoxygenation reactions. Hydroxyalkylation/alkylation of acetoin with 2-methylfuran was investigated over a series of solid acid catalysts. Among the investigated candidates, zirconia supported trifluoromethanesulfonic acid showed the highest activity and stability. In the aldol condensation step, a basic ionic liquid [H3N+-CH2-CH2-OH][CH3COO-] was identified as an efficient and recyclable catalyst for the reactions of acetoin with furan based aldehydes. The scope of the process has also been studied by reacting acetoin with other aldehydes, and it was found that abnormal condensation products were formed from the reactions of acetoin with aromatic aldehydes through an aldol condensation-pinacol rearrangement route when amorphous aluminium phosphate was used as a catalyst. And the final hydrodeoxygenation step could be achieved by using a simple and handy Pd/C + H-beta zeolite system, and no or a negligible amount of oxygenates was observed after the reaction. Excellent selectivity was also observed using the present system, and the clean formation of hydrocarbons with a narrow distribution of alkanes occurred in most cases.
