77572-66-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77572-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77572-66:
(7*7)+(6*7)+(5*5)+(4*7)+(3*2)+(2*6)+(1*6)=168
168 % 10 = 8
So 77572-66-8 is a valid CAS Registry Number.

Regiodivergent Conversion of Alkenes to Branched or Linear Alkylpyridines

Kim, Minseok,Shin, Sanghoon,Koo, Yejin,Jung, Sungwoo,Hong, Sungwoo

supporting information, p. 708 - 713 (2022/01/20)

Herein we report a practical protocol for the visible-light-induced regiodivergent radical hydropyridylation of unactivated alkenes using pyridinium salts. This approach provides a unified synthetic platform to control the regioselectivity of the synthesis of linear or branched C4-alkylated pyridines. A remarkable selectivity switch from the anti-Markovnikov to the Markovnikov product can be achieved by the addition of tetrabutylammonium bromide. The versatility of this protocol is further demonstrated based on the late-stage functionalization in pharmaceuticals.

Palladium(II) acetate catalyzed acylative cleavage of cyclic and acyclic ethers under neat conditions

Fotie, Jean,Adolph, Brandy R.,Bhatt, Shreya V.,Grimm, Casey C.

supporting information, p. 4648 - 4651 (2017/11/15)

During the development of a palladium catalyzed C–H activation cross-coupling reaction involving acyl halides, it was noted that palladium(II) acetate catalyzes the acylative cleavage of tetrahydrofuran (used as a solvent) at room temperature to afford the corresponding 4-chlorobutyl ester derivative. After optimization, the reaction was shown to work well with epoxides, oxetane and tetrahydrofuran, but only barely with oxanes at room temperature. Acyclic ethers systematically failed to react under similar conditions, but underwent complete conversion in a microwave reactor at 100 °C.
