17909-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17909-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17909-51:
(7*1)+(6*7)+(5*9)+(4*0)+(3*9)+(2*5)+(1*1)=132
132 % 10 = 2
So 17909-51-2 is a valid CAS Registry Number.

A simple method for mild oxidation of α-hydroxysilanes to provide aroylsilanes

Patrocinio,Moran

, p. 2457 - 2461 (2001)

Potassium permanganate supported onto alumina in hexane-water is a good oxidizing agent to convert α-hydroxysilanes into acylsilanes. This mild oxidation afforded aroylsilanes having electron-donating groups attached to the aromatic ring, in 70-86% yield.

Tertiary α-Silyl Alcohols by Diastereoselective Coupling of 1,3-Dienes and Acylsilanes Initiated by Enantioselective Copper-Catalyzed Borylation

Feng, Jian-Jun,Oestreich, Martin

, p. 8211 - 8215 (2019/05/27)

An efficient synthesis of functionalized tertiary α-silyl alcohols by an enantio- and diastereoselective copper-catalyzed three-component coupling of 1,3-dienes, bis(pinacolato)diboron, and acylsilanes is reported. The reaction proceeds well with different 1,3-dienes and a broad range of aryl- as well as alkenyl- but also alkyl-substituted acylsilanes. The target compounds are formed with high regio-, diastereo-, and enantioselectivity (up to 99 % ee and d.r. >20:1) and are highly versatile synthetic building blocks.

Zinc-Catalyzed Synthesis of Acylsilanes Using Carboxylic Acids and a Silylborane in the Presence of Pivalic Anhydride

Tatsumi, Kenta,Tanabe, Sae,Tsuji, Yasushi,Fujihara, Tetsuaki

supporting information, p. 10130 - 10133 (2019/12/24)

Zinc-catalyzed synthesis of acylsilanes using carboxylic acids and a silylborane has been achieved in the presence of pivalic anhydride. Various carboxylic acids were converted to the corresponding acylsilanes. The in situ formation of mixed anhydrides wa
