Check Digit Verification of cas no

The CAS Registry Mumber 38447-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,4 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38447-68:
(7*3)+(6*8)+(5*4)+(4*4)+(3*7)+(2*6)+(1*8)=146
146 % 10 = 6
So 38447-68-6 is a valid CAS Registry Number.

Synthesis of selenol esters: Palladium-catalyzed coupling of phenyl tributylstannyl selenide with aryl iodides and carbon monoxide

Nishiyama, Yutaka,Tokunaga, Keiji,Kawamatsu, Hiroaki,Sonoda, Noboru

, p. 1507 - 1509 (2002)

It was found that palladium complex catalyzed three-component coupling of phenyl tributylstannyl selenide with aryl iodides and carbon monoxide to afford the corresponding selenol esters in moderate to good yields.

Photoredox-Enabled Chromium-Catalyzed Alkene Diacylations

, p. 1879 - 1885 (2022/02/07)

Transition-metal-catalyzed cross-coupling reactions are a powerful tool to construct carbon-carbon bonds in modern synthetic chemistry. Chromium catalysis is much less developed compared with the widely used palladium and nickel catalysis. Herein, we repo

Palladium-Catalyzed Carbonylative Synthesis of Aryl Selenoesters Using Formic Acid as an Ex Situ CO Source

Yano De Albuquerque, Danilo,Teixeira, Wystan K. O.,Sacramento, Manoela Do,Alves, Diego,Santi, Claudio,Schwab, Ricardo S.

, p. 595 - 605 (2022/01/12)

A new catalytic protocol for the synthesis of selenoesters from aryl iodides and diaryl diselenides has been developed, where formic acid was employed as an efficient, low-cost, and safe substitute for toxic and gaseous CO. This protocol presents a high functional group tolerance, providing access to a large family of selenoesters in high yields (up to 97%) while operating under mild reaction conditions, and avoids the use of selenol which is difficult to manipulate, easily oxidizes, and has a bad odor. Additionally, this method can be efficiently extended to the synthesis of thioesters with moderate-to-excellent yields, by employing for the first time diorganyl disulfides as precursors.

Photocatalytic regiospecific p-silylation of arenes has been achieved by the coupling of in situ generated silyl radical with arene radical cation. The strategy involves reductive activation of PhSe-SiR3 and single electron transfer from the electron rich

Nickel-Catalyzed Intramolecular Decarbonylative Coupling of Aryl Selenol Esters

Bai, Jin-Hua,Qi, Xiu-Juan,Sun, Wei,Yu, Tian-Yang,Xu, Peng-Fei

supporting information, p. 2084 - 2088 (2021/03/01)

This report describes a method for Ni-catalyzed intramolecular decarbonylative coupling, which enables the conversion of areneselenol esters to diaryl selenides. The inexpensive and readily available catalyst can be employed under mild reaction conditions for the construction of structurally diverse diaryl selenides, including heterocyclic and natural product derivatives. (Figure presented.).

Thioesterification and Selenoesterification of Amides via Selective N-C Cleavage at Room Temperature: N-C(O) to S/Se-C(O) Interconversion

The direct nucleophilic addition to amides represents an attractive methodology in organic synthesis that tackles amidic resonance by ground-state destabilization. This approach has been recently accomplished with carbon, nitrogen and oxygen nucleophiles.

Iron(III)-catalyzed synthesis of selenoesters from α-amino carbonyl derivatives at room temperature

Chatterjee, Rana,Mukherjee, Anindita,Santra, Sougata,Zyryanov, Grigory V.,Majee, Adinath

, (2019/09/30)

An Fe(III)-catalyzed efficient method has been developed for the synthesis of selenoester derivatives in high yields through the coupling of α-amino carbonyl/glycine derivatives and diselenides under ambient air. A library of benzoselenoate derivatives having a variety of substituents has been synthesized. A plausible reaction pathway has been predicted. Experimental results suggest that the reaction proceeds through a radical pathway. Operational simplicity, compatibility with various α-amino carbonyls and diselenides, high yields, fast reaction and mild reaction conditions are the notable advantages of this procedure. We have also shown the practical application of the synthesized selenoesters which is useful to generate peptide bonds in biological sciences.

A mild, practical, and simple procedure for phenyl selenoesters synthesis from several anhydrides and diphenyl diselenide was developed. This transition-metal-free method provides a straightforward entry to storable Fmoc-amino acid selenoesters which are effective chemoselective acylating reagents. An application to oligopeptide synthesis was illustrated.
