27748-51-2

(Z)-2-Nitro-2-pentene is an organic compound with the molecular formula C5H9NO2. It is a positional isomer of 2-pentene, where a nitro group (-NO2) is attached to the second carbon atom in the (Z) configuration, indicating that the nitro group and the double bond are on the same side of the molecule when viewed along the longest carbon chain. This yellowish liquid is a nitroalkene, which is a class of compounds containing both a nitro group and a carbon-carbon double bond. It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactivity, (Z)-2-Nitro-2-pentene should be handled with care, as it can undergo various chemical reactions, such as reduction, addition, and rearrangement.

27748-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27748-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,4 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27748-51:
(7*2)+(6*7)+(5*7)+(4*4)+(3*8)+(2*5)+(1*1)=142
142 % 10 = 2
So 27748-51-2 is a valid CAS Registry Number.

Facile and highly stereoselective one-pot synthesis of either (E)- or (Z)-nitro alkenes

Fioravanti, Stefania,Pellacani, Lucio,Tardella, Paolo A.,Vergari, Maria Cecilia

, p. 1449 - 1451 (2008)

(Chemical Equation Presented) Aliphatic aldehydes were reacted with nitro alkanes in the presence of catalytic amounts of piperidine over 4 A molecular sieves. Simply by changing reaction conditions (solvent and temperature) it is possible to control the stereochemical outcome of the reactions, obtaining pure (E)- and (Z)-nitro alkenes in high to excellent yields. The role of molecular sieves on the stereochemical control seems crucial in addition to that of piperidine, especially for the synthesis of the Z isomer.

A Convenient Procedure for the Conversion of (E)-Nitroalkenes to (Z)-Nitroalkenes via erythro-β-Nitroselenides

Ono, Noboru,Kamimura, Akio,Kawai, Takashi,Kaji, Aritsune

, p. 1550 - 1551 (2007/10/02)

erythro-Selective conjugate addition of benzeneselenol to (E)-nitroalkenes and subsequent syn-elimination of benzeneselenenic acid provide a new method for the conversion of (E)-nitroalkenes into (Z)-nitroalkenes.
