23866-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23866-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,6 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23866-67:
(7*2)+(6*3)+(5*8)+(4*6)+(3*6)+(2*6)+(1*7)=133
133 % 10 = 3
So 23866-67-3 is a valid CAS Registry Number.

Study on Palladium(II)-Catalyzed Mono-1-alkenylation of 9 H -Carbazoles

Guo, Dongdong,Li, Bin,Gao, Wenmei,Zhang, Wuxia,Wang, Yongqiang,Zhao, Jinzhong

, p. 800 - 804 (2021)

A general and efficient method is reported for the direct mono-1-alkenylation of 9 H -carbazole molecules with divalent palladium as a catalyst and an N -(2-pyridyl)sulfanyl directing group. This method also provides an efficient synthetic route for the s

Color tuning based on a six-membered chelated iridium(III) complex with aza-aromatic ligand

Zhu, Rui,Lin, Jian,Wen, Gui-An,Liu, Shu-Juan,Wan, Jun-Hua,Feng, Jia-Chun,Fan, Qu-Li,Zhong, Gao-Yu,Wei, Wei,Huang, Wei

, p. 1668 - 1669 (2005)

A six-membered chelated iridium complex containing aza-aromatic ligand is prepared. Emission color tuning from yellow to deep red is observed for electroluminescent devices with different doping concentrations. Copyright

Palladium-Catalyzed Pyridine-Directed Regioselective Oxidative C–H Acylation of Carbazoles by Using Aldehydes as the Acyl Source

Maiti, Subhadip,Burgula, Laxminarayana,Chakraborti, Gargi,Dash, Jyotirmayee

, p. 332 - 340 (2017)

We herein report a highly regioselective reaction for the palladium-catalyzed oxidative acylation of carbazole derivatives with various aromatic and aliphatic aldehydes as the acyl source. The carbazole derivatives are N-protected with an easily removable pyridine moiety, which directs the Pd-catalyzed ortho acylation to occur at the C-1 and C-8 positions. The reactions of dibromo- and diiodo-substituted N-pyridylcarbazole derivatives, however, provide only the 1-acylated products. This method can be applied to a broad scope of substrates. A reaction mechanism has also been proposed.
