Check Digit Verification of cas no

The CAS Registry Mumber 29555-16-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 29555-16:
(7*2)+(6*9)+(5*5)+(4*5)+(3*5)+(2*1)+(1*6)=136
136 % 10 = 6
So 29555-16-6 is a valid CAS Registry Number.

Development of new and efficient copper(ii) complexes of hexyl bis(pyrazolyl)acetate ligands as catalysts for allylic oxidation

Metal-free allylic C-H nitrogenation, oxygenation, and carbonation of alkenes by thianthrenation

Du, Hai-Wu,Liu, Ming-Shang,Shu, Wei

, p. 1003 - 1008 (2022/02/02)

Selective functionalization of allylic C-H bonds into other chemical bonds is among the most straightforward and attractive, yet challenging transformations. Herein, a transition-metal-free protocol for direct allylic C-H nitrogenation, oxygenation, and carbonation of alkenes by thianthrenation was developed. This operationally simple protocol allows for the unified allylic C-H amination, esterification, etherification, and arylation of vinyl thianthrenium salts. Notably, the reaction furnishes multialkyl substituted allylic amines, ammonium salts, sulfonyl amides, esters, and ethers in good yields. The reaction proceeds under mild conditions with excellent functional group tolerance and could be applied to late-stage allylation of natural products, drug molecules and peptides with excellent chemoselectivity.

Copper porphyrin-catalyzed cross dehydrogenative coupling of alkanes with carboxylic acids: Esterification and decarboxylation dual pathway

Chen, Xiao-Yan,Yang, Shuang,Ren, Bao-Ping,Shi, Lei,Lin, Dong-Zi,Zhang, Hao,Liu, Hai-Yang

, (2021/08/13)

A dual-functional copper porphyrin-catalyzed cross dehydrogenative coupling (CDC) of carboxylic acids with alkanes was reported firstly. The reaction gives allylic esters or alkylalkenes depending on the carboxylic acid substrates. Copper porphyrin catalyzed CDC method has the superiority of short reaction time, good functional group tolerance, base and solvent free, producing target products in an atom-economic manner.

Copper-catalyzed oxidative dehydrogenative functionalization of alkanes to allylic esters

Mondal, Rakesh,Chakraborty, Gargi,van Vliet, Kaj M.,van Leest, Nicolaas P.,de Bruin, Bas,Paul, Nanda D.

supporting information, (2019/11/11)

Herein, we report a general, efficient and solvent-free method for the one-pot synthesis of allylic esters via dehydrogenation of unactivated alkanes and subsequent oxidative cross coupling with different substituted carboxylic acids. A simple, well defined and air stable Cu(II)-complex, [Cu(MeTAA)], featuring a tetraaza-macrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)) is used as the catalyst. A wide variety of substituted allylic esters were synthesized in high yields starting from readily available starting materials. Control reactions were carried out to understand the reaction sequence and the plausible mechanism.

Bimetallic Radical Redox-Relay Catalysis for the Isomerization of Epoxides to Allylic Alcohols

Ye, Ke-Yin,Mccallum, Terry,Lin, Song

supporting information, (2019/06/24)

Organic radicals are generally short-lived intermediates with exceptionally high reactivity. Strategically, achieving synthetically useful transformations mediated by organic radicals requires both efficient initiation and selective termination events. Here, we report a new catalytic strategy, namely, bimetallic radical redox-relay, in the regio- and stereoselective rearrangement of epoxides to allylic alcohols. This approach exploits the rich redox chemistry of Ti and Co complexes and merges reductive epoxide ring opening (initiation) with hydrogen atom transfer (termination). Critically, upon effecting key bond-forming and -breaking events, Ti and Co catalysts undergo proton transfer/electron transfer with one another to achieve turnover, thus constituting a truly synergistic dual catalytic system.

Iron-catalyzed esterification of allylic sp3 C–H bonds with carboxylic acids: Facile access to allylic esters

Lu, Bing,Zhu, Fan,Wang, Dan,Sun, Hongmei,Shen, Qi

supporting information, p. 2490 - 2494 (2017/05/31)

The first general and efficient iron-catalyzed esterification of allylic sp3 C–H bonds with carboxylic acids using ionic iron(III) complexes (1–4) as a catalyst and DTBP (DTBP?=?di-tert-butyl peroxide) as an oxidant is achieved. A variety of allylic esters were synthesized in good to excellent yields using the ionic iron(III) complex 2 as a catalyst in a 5?mol% loading. This reaction is characterized by its high efficiency, broad substrate scope with excellent steric hindrance tolerance and good functional group compatibility.

Copper-catalyzed oxidative dehydrogenative carboxylation of unactivated alkanes to allylic esters via alkenes

Tran, Ba L.,Driess, Matthias,Hartwig, John F.

supporting information, p. 17292 - 17301 (2015/02/02)

We report copper-catalyzed oxidative dehydrogenative carboxylation (ODC) of unactivated alkanes with various substituted benzoic acids to produce the corresponding allylic esters. Spectroscopic studies (EPR, UV-vis) revealed that the resting state of the catalyst is [(BPI)Cu(O2CPh)] (1-O2CPh), formed from [(BPI)Cu(PPh3)2], oxidant, and benzoic acid. Catalytic and stoichiometric reactions of 1-O2CPh with alkyl radicals and radical probes imply that C-H bond cleavage occurs by a tert-butoxy radical. In addition, the deuterium kinetic isotope effect from reactions of cyclohexane and d12-cyclohexane in separate vessels showed that the turnover-limiting step for the ODC of cyclohexane is C-H bond cleavage. To understand the origin of the difference in products formed from copper-catalyzed amidation and copper-catalyzed ODC, reactions of an alkyl radical with a series of copper-carboxylate, copper-amidate, and copper-imidate complexes were performed. The results of competition experiments revealed that the relative rate of reaction of alkyl radicals with the copper complexes follows the trend Cu(II)-amidate > Cu(II)-imidate > Cu(II)-benzoate. Consistent with this trend, Cu(II)-amidates and Cu(II)-benzoates containing more electron-rich aryl groups on the benzamidate and benzoate react faster with the alkyl radical than do those with more electron-poor aryl groups on these ligands to produce the corresponding products. These data on the ODC of cyclohexane led to preliminary investigation of copper-catalyzed oxidative dehydrogenative amination of cyclohexane to generate a mixture of N-alkyl and N-allylic products.
