However, if the solute is polar while the solvent is nonpolar, or vice versa, a mixture will be formed instead. This generalization … WebThis "nucleophilic" carbon then attacks the carbonyl carbon of the cinnamaldehyde, resulting in a new carbon-carbon bond. The process the repeats with the formation of a carbanion on the alpha carbon that was originally on the other side of the acetone carbonyl group. The final product is 1,9-diphenyl-1,3,6,8-nonatetraen-5-one (dicinnamalacetone). fischerbastion budapest
