851591-16-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 851591-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,5,9 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 851591-16:
(8*8)+(7*5)+(6*1)+(5*5)+(4*9)+(3*1)+(2*1)+(1*6)=177
177 % 10 = 7
So 851591-16-7 is a valid CAS Registry Number.

6-Arylphenanthridines from Aryl o-Biaryl Ketones with 1,1,1,3,3,3-Hexamethyldisilazane and Molecular Iodine

Kobayashi, Eiji,Kishi, Atsushi,Togo, Hideo

, p. 7335 - 7347 (2019/11/22)

Warming treatment of aryl o-biaryl ketones with 1,1,1,3,3,3-hexamethyldisilazane in the presence of Sc(OTf)3 in toluene, followed by the reaction with molecular iodine and K2CO3 in a mixture of THF and methanol at 60 °C gave the corresponding 6-arylphenanthridines in good to moderate yields. The present reaction is a one-pot method for the preparation of 6-arylphenanthridines from aryl o-biaryl ketones through the cyclization of imino-nitrogen-centered radicals that were generated from N-iodo aryl o-biaryl ketimines formed from the reaction of aryl biaryl ketimines with molecular iodine.

P,N,N-Pincer nickel-catalyzed cross-coupling of aryl fluorides and chlorides

Wu, Dan,Wang, Zhong-Xia

, p. 6414 - 6424 (2014/08/18)

P,N,N-Pincer nickel complexes [Ni(Cl){N(2-R2PC6H 4)(2′-Me2NC6H4)}] (R = Ph, 3a; R = Pri, 3b; R = Cy, 3c) were synthesized and their catalysis toward the Kumada or Negishi cross-coupling reaction of aryl fluorides and chlorides was evaluated. Complex 3a effectively catalyzes the cross-coupling of (hetero)aryl fluorides with aryl Grignard reagents at room temperature. Complex 3a also catalyzes the cross-coupling of (hetero)aryl chlorides and arylzinc reagents at 80 °C with low catalyst loadings and good functional group compatibility. the Partner Organisations 2014.

Stereoselective synthesis of folded luminogens with arene-arene stacking interactions and aggregation-enhanced emission

Zhao, Zujin,He, Bairong,Nie, Han,Chen, Bin,Lu, Ping,Qin, Anjun,Tang, Ben Zhong

supporting information, p. 1131 - 1133 (2014/01/17)

Tetraphenylethene derivatives with a folded Z-conformation and aggregation-enhanced emission characteristics are synthesized from 2-arylbenzophenones. The intramolecular rotation of the folded luminogens is partially suppressed, resulting in improved emission efficiencies in solutions.
