Kinetics of decarboxylation of b-pyridylacrylic acids
Kinetics of decarboxylation of b-pyridylacrylic acids. Stoicescu, C. (Chem. Pharm. Res. Inst., Bucharest, Rom.). Rev. Roum. Chim., 28(2), 147-50 (English) 1983. CODEN: RRCHAX. ISSN: 0035-3930. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The decarboxylation kinetics, Hammett r, and isokinetic b were detd.There are some commonly used reagents with their cas registry numbers 7340-22-9 and 7440-50-8 in this article. for the decarboxylation of b-pyridylacrylic acids in quinoline over Cu. Inductive effects were greater than resonance effects. The transition state for a zwitterionic mechanism involving a Cu complex was discussed. .
