10264-22-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10264-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,6 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10264-22:
(7*1)+(6*0)+(5*2)+(4*6)+(3*4)+(2*2)+(1*2)=59
59 % 10 = 9
So 10264-22-9 is a valid CAS Registry Number.

Phototriggered Active Alkyne Generation from Cyclopropenones with Visible Light-Responsive Photocatalysts

Mishiro, Kenji,Kimura, Takeshi,Furuyama, Taniyuki,Kunishima, Munetaka

, p. 4101 - 4105 (2019)

A photocatalytic active alkyne generation reaction was developed using cyclopropenone as a starting reagent. Visible light-responsive photocatalysts induced cyclopropenone decarbonylation. The resulting highly reactive alkyne could be used directly, witho

Ammonia-borane as a Catalyst for the Direct Amidation of Carboxylic Acids

Ramachandran, P. Veeraraghavan,Hamann, Henry J.

supporting information, p. 2938 - 2942 (2021/05/04)

Ammonia-borane serves as an efficient substoichiometric (10%) precatalyst for the direct amidation of both aromatic and aliphatic carboxylic acids. In situ generation of amine-boranes precedes the amidation and, unlike the amidation with stoichiometric amine-boranes, this process is facile with 1 equiv of the acid. This methodology has high functional group tolerance and chromatography-free purification but is not amenable for esterification. The latter feature has been exploited to prepare hydroxyl- and thiol-containing amides.

Studies of the Electronic Effects of Zinc Cluster Catalysts and Their Application to the Transesterification of β-Keto Esters

Agura, Kazushi,Hayashi, Yukiko,Wada, Mari,Nakatake, Daiki,Mashima, Kazushi,Ohshima, Takashi

supporting information, p. 1548 - 1554 (2016/06/01)

The electronic effects of tetranuclear zinc cluster catalysts on transesterification were investigated by changing the carboxylate ligands in the clusters. High catalyst activity crucially depended on the balance between Lewis acidity and Br?nsted basicity of the catalyst; this was consistent with the dual activation of both the electrophile and nucleophile by the cooperative zinc centers. In addition, tetranuclear zinc cluster catalysts achieved the transesterification of β-keto esters with unprecedented levels of broad substrate generality, in which a newly developed pentafluoropropionate-bridged zinc cluster and 4-dimethylaminopyridine additive greatly improved the reactivity of sterically congested α- and α,α-disubstituted β-keto esters. Lewis versus Br?nsted: High catalyst activity of zinc clusters on transesterification crucially depend on a balance between Lewis acidity and Br?nsted basicity of the catalyst. Zinc clusters, including a newly developed pentafluoropropionate-bridged zinc cluster, achieved the transesterification of β-keto esters with unprecedented levels of broad substrate generality (see figure).
