625-46-7

3-Nitropropene, also known as β-nitropropene or propene, 3-nitro-, is a chemical compound with the molecular formula C3H5NO2. It is a colorless to pale yellow liquid with a pungent odor and is an important intermediate in the synthesis of various chemicals, including pharmaceuticals, dyes, and agrochemicals. 3-Nitropropene is produced through the nitration of propene, a process that involves the reaction of propene with a mixture of nitric acid and sulfuric acid. Propene, 3-nitro- is highly reactive and can undergo various chemical reactions, such as reduction, hydrolysis, and substitution, making it a versatile building block in organic synthesis. Due to its reactivity and potential use in the production of explosives, 3-nitropropene is considered a hazardous substance and requires proper handling and storage.

625-46-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 625-46-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 625-46:
(5*6)+(4*2)+(3*5)+(2*4)+(1*6)=67
67 % 10 = 7
So 625-46-7 is a valid CAS Registry Number.

Desilylative Nitration of Alkyl- and Allylsilanes with Nitronium Salts

Olah, George A.,Rochin, Christophe

, p. 701 - 702 (2007/10/02)

Desilylative nitration of methyl- and ethylsilanes with nitronium tetrafluoroborate in sulfolane solution gives nitromethane and nitroethane, respectively.Higher alkylsilanes are also nitrated, but the reactions are followed by HNO2 elimination.The method represents the first successful nitrodesilylations at saturated carbon.Allylsilanes react cleanaly with NO2BF4 in methylene chloride solution to give nitropropanes in good to excellent yield.These reactions, however, involve initial attack by NO2+ on the allylic ?-system followed by fluoride-induced trimethylsilyl elimination and not direct desilylative nitration at saturated carbon. 1-(Trimethylsilyl)but-2-ene gives exclusive secondary 3-nitrobut-1-ene and not the primary direct nitrodesilylation product 1-nitrobut-2-ene.
