Lithium, (methyldiphenylsilyl)-, also known as methyldiphenylsilyllithium, is an organometallic compound with the chemical formula C13H13LiSi. It is a colorless, highly reactive, and moisture-sensitive solid, often used as a reagent in organic synthesis. Lithium, (methyldiphenylsilyl)- is formed by the reaction of lithium metal with methyldiphenylsilane, resulting in a lithium-silane complex. Methyldiphenylsilyllithium is commonly employed as a nucleophile in various organic reactions, such as the formation of carbon-carbon bonds and the synthesis of silyl ethers. Due to its reactivity, it must be handled with extreme care under an inert atmosphere, typically using Schlenk techniques or glovebox conditions.

3839-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3839-30-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3839-30:
(6*3)+(5*8)+(4*3)+(3*9)+(2*3)+(1*0)=103
103 % 10 = 3
So 3839-30-3 is a valid CAS Registry Number.

SILYLCUPRATION OF ACETYLENES

Chen, Hsiao-Ming,Oliver, John P.

, p. 255 - 260 (1986)

Several organosilylcuprates have been prepared and their reactions with acetylenes examined.It has been shown that LiCu2 adds to acetylenes in only one manner, i.e. with cis addition and the Si(SiMe3)3 group in the least hindered cite as shown

Synthesis of Alkyl Silanes via Reaction of Unactivated Alkyl Chlorides and Triflates with Silyl Lithium Reagents

Mallick, Shubhadip,Würthwein, Ernst-Ulrich,Studer, Armido

supporting information, p. 6568 - 6572 (2020/09/02)

The reaction of unactivated secondary and primary alkyl chlorides as well as primary alkyl triflates with silyl lithium reagents to access tetraorganosilanes is reported. These nucleophilic substitutions proceed in the absence of any transition metal catalyst under mild conditions in moderate to very good yields. The silyl lithium reagents are readily generated from the corresponding commercially available chlorosilanes. Enantioenriched secondary alkyl chlorides react with high stereospecificity under inversion of configuration.
