389-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 389-42-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 389-42:
(5*3)+(4*8)+(3*9)+(2*4)+(1*2)=84
84 % 10 = 4
So 389-42-4 is a valid CAS Registry Number.

Photoinduced Hydroarylation and Cyclization of Alkenes with Luminescent Platinum(II) Complexes

Cheng, Hanchao,Lam, Tsz-Lung,Liu, Yungen,Tang, Zhou,Che, Chi-Ming

supporting information, p. 1383 - 1389 (2020/11/30)

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron-deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible-light (410 nm) irradiation, affording anti-Markovnikov hydroarylated compounds in up to 95 % yield. Besides, a protocol for [Pt(O^N^C^N)]-catalyzed intramolecular photocyclization of acrylanilides to give structurally diverse 3,4-dihydroquinolinones has been developed.

Br?nsted Acid Catalyzed Peterson Olefinations

Britten, Thomas K.,McLaughlin, Mark G.

, p. 301 - 305 (2019/12/25)

A mild and facile Peterson olefination has been developed employing low catalyst loading of the Br?nsted acid HNTf2. The reactions are typically performed at room temperature, with the reaction tolerant to a range of useful functionalities. Furthermore, we have extended this methodology to the synthesis of enynes.

Halogenation of 1,1-diarylethylenes by N-halosuccinimides

Zhang, Ge,Bai, Rui-Xue,Li, Chu-Han,Feng, Chen-Guo,Lin, Guo-Qiang

supporting information, p. 1658 - 1662 (2018/12/11)

An efficient method for the preparation of 2,2-diarylvinyl halides from the corresponding 1,1-diarylethylenes has been developed. N-Halosuccinimides (N-bromosuccinimide or N-chlorosuccinimide) were used as the halogenation reagents. The practicability of this method is highlighted by its simple operation, broad substrate scope and capability for large-scale reaction.
