17180-39-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17180-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,8 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17180-39:
(7*1)+(6*7)+(5*1)+(4*8)+(3*0)+(2*3)+(1*9)=101
101 % 10 = 1
So 17180-39-1 is a valid CAS Registry Number.

Iron-Catalyzed Methylation Using the Borrowing Hydrogen Approach

Polidano, Kurt,Allen, Benjamin D. W.,Williams, Jonathan M. J.,Morrill, Louis C.

, p. 6440 - 6445 (2018)

A general iron-catalyzed methylation has been developed using methanol as a C1 building block. This borrowing hydrogen approach employs a Kn?lker-type (cyclopentadienone)iron carbonyl complex as catalyst (2 mol %) and exhibits a broad reaction scope. A variety of ketones, indoles, oxindoles, amines, and sulfonamides undergo mono- or dimethylation in excellent isolated yields (>60 examples, 79% average yield).

Palladium-Catalyzed Synthesis of α-Methyl Ketones from Allylic Alcohols and Methanol

Biswal, Priyabrata,Samser, Shaikh,Meher, Sushanta Kumar,Chandrasekhar, Vadapalli,Venkatasubbaiah, Krishnan

, p. 413 - 419 (2021/11/01)

One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.

Expedient Synthesis of Ketones via N-Heterocyclic Carbene/Nickel-Catalyzed Redox-Economical Coupling of Alcohols and Alkynes?

Li, Yu-Qing,Li, Feng,Shi, Shi-Liang

supporting information, p. 1035 - 1039 (2020/06/30)

An N-heterocyclic carbene/nickel-catalyzed direct coupling of alcohols and internal alkynes to form α-branched ketones has been developed. This methodology provides a new approach to afford branched ketones, which are difficult to access through the hydroacylation of simple internal alkenes with aldehydes. This redox-neutral and redox-economical coupling is free from any oxidative or reductive additives as well as stoichiometric byproducts. These reactions convert both benzylic and aliphatic alcohols and alkynes, two basic feedstock chemicals, into various α-branched ketones in a single chemical step.
