1112-49-8 Usage

General Description

Triethyliodosilane is a chemical compound with the formula Si(C2H5)3I. It falls under the category of organosilicon compounds and, in particular, is considered an alkylsilane. Triethyliodosilane, in industrial chemistry, is used as a source of silicon to prepare silicon-containing polymers, ceramics, and specific catalytic agents on surfaces. It is also used in the production of semiconductors. It's key to note that it's a hazardous substance that can cause eye, skin, and respiratory irritation upon contact or inhalation. Therefore, every user should pay attention to safety guidelines when handling this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 1112-49-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1112-49:
(6*1)+(5*1)+(4*1)+(3*2)+(2*4)+(1*9)=38
38 % 10 = 8
So 1112-49-8 is a valid CAS Registry Number.

Regio- And Stereoselective Hydroiodination of Internal Alkynes with Ex Situ-Generated HI

Nozawa-Kumada, Kanako,Noguchi, Koto,Akada, Tomoya,Shigeno, Masanori,Kondo, Yoshinori

supporting information, p. 6659 - 6663 (2021/09/08)

Herein, we report an efficient and practical hydroiodination of internal alkynes using HI generated ex situ from the readily available triethylsilane and I2. This system offers high regio- and stereoselectivity to afford (E)-vinyl iodides in good yields under mild conditions. Furthermore, the hydroiodination reaction shows high functional group tolerance toward alkyl, methoxy, halogen, trifluoromethyl, cyano, ester, halomethyl, acid-sensitive silyl ether, and acetal moieties.

Acyl iodides in organic synthesis: IX. Cleavage of the Si-O-C and Si-O-Si moieties

Voronkov,Trukhina,Belousova,Kuznetsova,Vlasova

, p. 501 - 506 (2008/02/02)

Reactions of acyl iodides RCOI (R = Me, Ph) with organosilicon compounds involve cleavage of the Si-O-C and Si-O-Si fragments. Acetyl iodide reacts with alkyl(alkoxy)silanes with evolution of heat, and cleavage of the Si-O bond results in the formation of oligo-or polysiloxanes, alkyl iodides, and alkyl acetates. 1,3-Diacetoxytetramethyldisiloxane is formed in the reaction of acetyl iodide with dimethoxy(dimethyl)silane. Acyl iodides readily react with 1-ethoxysilatrane to give 1-acyloxysilatranes as a result of cleavage of the C-O bond. The reaction of acetyl iodide with hexaethyldisiloxane yields triethylsilyl acetate and triethyliodosilane, while in the reaction with octamethyltrisiloxane iodo(trimethyl)silane and dimethyl(trimethylsiloxy)silyl acetate are obtained.
