## Abstract ^1^H NMR spectra of 26 substituted chalcones (3βarylβ1 phenylβ2βpropeneβ1βones and 1βarylβ3βphenylβ2βpropeneβ1βones) have been studied. The chemical shifts of the Ξ± and Ξ² protons to the carbonyl group were correlated with Hammett sΜ parameters. To gain information on the effect of the t
Anions of allylmeldrum's acids reacted with phenyl(propynyl)iodonium salt to produce bicyclo[3.1.0]hex-1-enes as the reactive intermediates through cyclopropanation reaction to yield various dimerization products. Depending on the substitution pattern on the intermediates, various dimeric products w
