175235-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175235-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,3 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 175235-76:
(8*1)+(7*7)+(6*5)+(5*2)+(4*3)+(3*5)+(2*7)+(1*6)=144
144 % 10 = 4
So 175235-76-4 is a valid CAS Registry Number.

Dithioacetalization or thioetherification of benzyl alcohols using 9-mesityl-10-methylacridinium perchlorate photocatalyst

Pramanik, Milan,Choudhuri, Khokan,Mathuri, Ashis,Mal, Prasenjit

supporting information, p. 10211 - 10214 (2020/09/21)

We report herein the use of 9-mesityl-10-methylacridinium perchlorate as the visible-light photocatalyst for dithioacetalization or thioetherification of benzyl alcohols in one pot using aerial dioxygen as a terminal oxidant. EPR analysis and Stern-Volmer

A Transition-Metal-Free and Base-Mediated Carbene Insertion into Sulfur-Sulfur and Selenium-Selenium Bonds: An Easy Access to Thio- and Selenoacetals

Arunprasath, Dhanarajan,Sekar, Govindasamy

, p. 698 - 708 (2017/02/23)

A transition-metal-free and base-mediated carbene insertion across sulfur-sulfur and selenium-selenium bonds has been developed by employing N-tosylhydrazone as a stable and safe carbene precursor. The ylide formation from carbene followed by Stevens rearrangement are considered to be the key steps. This thiol and selenol-free protocol delivers thioacetals and selenoacetals in good to excellent yields in short reaction time with good functional group tolerance. A one-pot synthesis involving in situ generation of tosylhydrazone has also been demonstrated. (Figure presented.).

Rhodium-catalyzed denitrogenative thioacetalization of N-sulfonyl-1,2,3-triazoles with disulfides: An entry to diverse transformation of terminal alkynes

Zhang, Hao,Wang, Hui,Yang, Haijun,Fu, Hua

, p. 6149 - 6153 (2015/06/08)

An efficient and useful rhodium-catalyzed denitrogenative thioacetalization of N-sulfonyl-1,2,3-triazoles has been developed for the first time. The protocol uses readily available N-sulfonyl-1,2,3-triazoles and diaryl disulfides as the starting materials. The corresponding hydrolytic and reductive products with thioacetals were obtained in good to excellent yields, and the reactions were carried out easily under mild conditions with tolerance of some functional groups. Furthermore, the generated thioacetals could be transformed into some useful compounds. Therefore, the present method provides a novel and valuable strategy for the diverse transformation of alkynes.
