28871-61-6 Usage
General Description
(Fluoromethyl)trimethylsilane is a colorless, flammable liquid with a fruity odor. It is primarily used as a reagent in organic synthesis to introduce the trimethylsilyl group (-Si(CH3)3) onto functional groups. This chemical is also used as a protective group in the synthesis of pharmaceuticals and agrochemicals. (Fluoromethyl)trimethylsilane is highly reactive and can undergo hydrolysis with water to produce hydrofluoric acid, a highly corrosive and toxic substance. Due to its flammability and potential for hazardous byproducts, (Fluoromethyl)trimethylsilane should be handled with caution and stored in a well-ventilated area away from sources of ignition.
Check Digit Verification of cas no
The CAS Registry Mumber 28871-61-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,7 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28871-61:
(7*2)+(6*8)+(5*8)+(4*7)+(3*1)+(2*6)+(1*1)=146
146 % 10 = 6
So 28871-61-6 is a valid CAS Registry Number.

Onium Ylide Chemistry. 2. Methylenedialkyloxonium Ylides
Olah, George A.,Doggweiler, Hans,Felberg, Jeff D.

We report evidence for the long sought after methylenedialkyloxonium ylides from methyloxonium ions by two independent routes, proving their intermediate formation through derived product analysis.Reaction of trimethyloxonium salts with sodium hydride results in competing proton abstraction besides methane formation (hydride methylation).Subsequent methylation of the formed methylenedimethyloxonium ylide by excess trimethyloxonum ion is resulting in C1 --> C2 conversion and formation of dimethylethyloxonium ion which with sodium hydride gives ethane (and methane) or by β-elimination ethylene.Besides expected fluoride alkylation products, i.e., alkyl fluorides and fluorosilanes, fluoride-induced desylilation of dimethyl((trimethylsilyl)methyl)oxonium tetrafluoroborate also results in the formation of methylenedimethyloxonium ylide giving via subsequent methylation and cleavage methyl ethyl ether and ethyl fluoride.
