HPLC of Formula: C5H8O2. I found the field of Chemistry very interesting. Saw the article gamma-C (sp(3))-H bond functionalisation of alpha,beta-unsaturated amides through an umpolung strategy published in 2020, Reprint Addresses Takeda, N; Ueda, M (corresponding author), Kobe Pharmaceut Univ, Higashinada Ku, Kobe, Hyogo 6588558, Japan.. The CAS is 80-59-1. Through research, I have a further understanding and discovery of (E)-2-Methylbut-2-enoic acid.
The nucleophilic gamma-phenylation and gamma-alkylation of alpha,beta-unsaturated amides have been developed. This umpolung reaction allows the regioselective introduction of phenyl and alkyl groups to a vinylketene N,O-acetal, which is generated in situ from an alpha,beta-unsaturated N-alkoxyamide, followed by N-O bond cleavage in a two-step, one-pot process.
HPLC of Formula: C5H8O2. About (E)-2-Methylbut-2-enoic acid, If you have any questions, you can contact Futaki, E; Takeda, N; Yasui, M; Shinada, T; Miyata, O; Ueda, M or concate me.
