2783-12-2

2-Nitro-1-butene, also known as 2-nitrobut-1-ene, is an organic compound with the chemical formula C4H7NO2. It is a yellowish liquid with a pungent odor and is used as an intermediate in the synthesis of various chemicals, including pharmaceuticals and dyes. The compound is characterized by its nitro group (-NO2) attached to the second carbon atom of a butene chain, which consists of four carbon atoms with a double bond between the first and second carbon atoms. 2-Nitro-1-butene is sensitive to heat and can decompose, releasing toxic nitrogen oxides. It is also considered a hazardous substance due to its potential health risks, such as causing irritation to the eyes, skin, and respiratory system, as well as being a potential carcinogen.

2783-12-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2783-12-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2783-12:
(6*2)+(5*7)+(4*8)+(3*3)+(2*1)+(1*2)=92
92 % 10 = 2
So 2783-12-2 is a valid CAS Registry Number.

One-pot asymmetric conjugate addition-trapping of zinc enolates by activated electrophiles

Rathgeb, Xavier,March, Sebastien,Alexakis, Alexandre

, p. 5737 - 5742 (2007/10/03)

The copper-catalyzed asymmetric conjugate addition of dialkyl zinc leads to homochiral zinc enolates. These intermediates were trapped in situ with activated allylic electrophiles, without the need of additional palladium catalysis. High trans selectivity
