Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 2689-65-8, is researched, SMILESS is IC1=CC=C(O1)C=O, Molecular C5H3IO2Journal, Collection of Czechoslovak Chemical Communications called Furan derivatives. LV. Kinetics of condensation of 5-nitrofurfuryl sulfones with aldehydes, Author is Knoppova, V.; Jurasek, A.; Kovac, J.; Guttmann, M., the main research direction is kinetics condensation aldehyde nitrofurfuryl sulfone; substituent effect condensation aldehyde nitrofurfuryl sulfone; reaction constant condensation aldehyde nitrofurfuryl sulfone; furfuryl sulfone condensation aldehyde nitrofurfuryl sulfone.COA of Formula: C5H3IO2.
The kinetics of the condensation of I with II (R = H, Me, iodo, Cl, Br, CO2Me NO2) or III (R = H, NO2, Cl, Br, CO2H, CO2Et, Me, MeO, NHAc) [to give, resp., the corresponding (E)-IV or (E)-V, examined in NH4OAc-piperidine at 118° or MeOH-piperidine at 40°, were 2nd order. The log k was linearly related with σp+. The pKa of I and of 5-nitrofurfuryl Me sulfone (VI) were determined and the rates of the condensation of I or VI with III (R = NO2) indicated that steric factors were more important in the condensation than was the sulfone acidity.
