4,4-Dichloro-1-butene is an organic compound with the chemical formula C4H6Cl2. It is a colorless liquid with a pungent odor and is used as an intermediate in the production of various chemicals, including pesticides and pharmaceuticals. 4,4-Dichloro-1-butene is characterized by its two chlorine atoms attached to the terminal carbon atoms of a butene chain, which gives it unique chemical properties. It is synthesized through the addition of chlorine to 1-butene, a process that involves the formation of a chloroalkene. Due to its reactivity and potential health and environmental concerns, 4,4-Dichloro-1-butene is typically handled with care in controlled industrial settings.

4279-19-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4279-19-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4279-19:
(6*4)+(5*2)+(4*7)+(3*9)+(2*1)+(1*9)=100
100 % 10 = 0
So 4279-19-0 is a valid CAS Registry Number.

Alkylations of Trichloromethylketones Effected by Trichloroacetate and a Complex Consecutive Reaction

Dehmlow, Eckehard V.,Raths, Hans-Christian

, p. 918 - 920 (2007/10/02)

A phase transfer reaction between the title ketones, sodium trichloroacetate, and an alkyl halide leads to 2a, b, 4, or 5.Whereas these compounds are fragmented by NaOH, sodium methoxide/methylmalonate/methanol give compound 8 from 5 in a complex series of consecutive rearrangements. - Key words: Trichloromethylketones, Phase Transfer Reaction

Methyl-halogenated Allyl Methyl Sulfoxides and Sulfones and the Synthesis of Halogenated Sulfines

Holoch, Jan,Sundermeyer, Wolfgang

, p. 269 - 278 (2007/10/02)

Allyl methyl sulfoxides R1R2R3C-S(O)-CH2CH=CH2 1a-7a (R1, R2, R3 = H, F, Cl, CF3) as well as the corresponding sulfones 1b-7b were synthesized.The sulfoxides substituted at the methyl group are in equilibrium with the allyl sulfenates R1R2R3-S-OCH2CH=CH2 depending on temperature and kind of substitution.By pyrolysis of the sulfoxides 2a, 3a, 4a, and 7a the sulfines Cl2C=SO and (CF3)2C=SO could be prepared, and evidence for the existence of the sulfines ClFC=SO and F2C=SO could be obtained.The new pentenes 12 and 14 are described.
