863098-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 863098-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,0,9 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 863098-32:
192 % 10 = 2
So 863098-32-2 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive 1,2-Dialkynylation of Alkenes Bearing an 8-Aminoquinoline Directing Group

Pan, Rui,Shi, Cong,Zhang, Dongquan,Tian, Yang,Guo, Songjin,Yao, Hequan,Lin, Aijun

supporting information, p. 8915 - 8920 (2019/11/14)

An unprecedented nickel-catalyzed reductive 1,2-dialkynylation of alkenes bearing an 8-aminoquinoline directing group has been developed. This method proceeded through a migratory insertion/reductive-coupling process under mild conditions with a wide substrate scope and good functional group tolerance, providing direct access to the synthetically flexible 1,5-diynes. Moreover, the 1,2-dialkynylation products could be further converted to borate-ester- or azide-functionalized 1,5-dienes, ditriazole, β-diyne primary amide, and trisubstituted benzene.

Palladium end-capped polyynes via oxidative addition of 1-haloalkynes to Pd(PPh3)4

Gulia, Nurbey,Pigulski, Bartlomiej,Szafert, Slawomir

, p. 673 - 682 (2015/05/12)

Reported here is the use of 1-haloacetylenes and 1-halopolyynes as synthons for the preparation of new palladium(II) end-capped polyynes. The 1-haloalkynes were obtained in a series of transformations from para-substituted bromoarenes that included Sonogashira coupling followed by halogenation and chain elongation via Cadiot-Chodkiewicz protocol. The key step for the synthesis of metal complexes was oxidative addition of 1-haloalkynes to Pd(PPh3)4, which allowed obtaining a series of metal compounds 1-5-CnX with carbon chains up to hexatriyne in 75-100% yield. All the compounds were characterized by NMR and HRMS or elemental analysis. The 13C spectra of the 1-haloalkynes showed interesting, although expected, shifts of the carbon chain atoms close to the halogen termini. X-ray crystal structures were obtained for three polyynes-two butadiynes (2-C4[Pd]Br and 3-C4[Pd]Br) and one hexatriyne (1-C6[Pd]Br)-and the latter is the first reported X-ray crystal structure of palladium end-capped hexatriyne.

Protection/deprotection-free syntheses and structural analysis of (keto-aryl)diynes

Osowska, Karolina,Lis, Tadeusz,Szafert, Slawomir

experimental part, p. 4598 - 4606 (2009/05/11)

The reactions of precursors 4-BrC6H4COR with TMSC≡CH (Sonogashira coupling) followed by in situ deprotection and subsequent dimerization gave thermally stable dimeric ketodiynes RCOC 6H4(C≡C)2C6
