2396-77-2 Usage
Description
Methyl 2-hexenoate has a green, musty, earthy, sweet, fruity odor
with a very powerful, sharp, green-fruity flavor. May be prepared
by boiling the corresponding acid with methanol in the presence
of concentrated H2S04 in chloroform and subsequent elimination of
water from the vapors using MgS04; also from 3-chloropropionic
acid methyl ester and anhydrous sodium acetate in acetic acid.

Check Digit Verification of cas no
The CAS Registry Mumber 2396-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2396-77:
(6*2)+(5*3)+(4*9)+(3*6)+(2*7)+(1*7)=102
102 % 10 = 2
So 2396-77-2 is a valid CAS Registry Number.

Linear Selective Isomerization/Hydroformylation of Unsaturated Fatty Acid Methyl Esters: A Bimetallic Approach
Gaide, Tom,Bianga, Jonas,Schlipk?ter, Kim,Behr, Arno,Vorholt, Andreas J.
, p. 4163 - 4171 (2017/06/19)
Herein, we report about the development of an isomerization/hydroformylation tandem reaction to selectively convert fatty acid methyl esters into asymmetric α,ω-functionalized aldehyde esters. An orthogonal tandem catalytic system consisting of a palladium-based isomerization catalyst and a rhodium-based hydroformylation catalyst was developed, using methyl 3-hexenoate as a model substrate. Using this catalyst, high yields (81% at 99% conversion) and regioselectivities (l/b-ratio of 98/2) toward the desired terminal hydroformylation product are obtained in the conversion of methyl 3-hexenoate under mild conditions. Ethyl 4-decenoate was subsequently applied as a second model substrate to identify challenges associated with the longer chain length of the unsaturated ester. Finally, methyl oleate was converted using the developed catalyst system. High aldehyde yields of 74% (at 99% conversion) with an l/b-ratio of 91/9 are obtained.
