Triphenylphosphine-catalyzed Michael addition of alcohols to acrylic compounds was written by Liu, Hai-Ling;Jiang, Huan-Feng;Wang, Yu-Gang. And the article was included in Chinese Journal of Chemistry in 2007.Reference of 763-69-9 The following contents are mentioned in the article:
A facile PPh3-catalyzed Michael addition of alcs. to acrylic compounds was described. The reaction was carried out in open air at reflux temperature in the presence of 10 mol% PPh3. Michael addition of saturated and unsaturated alcs. to acrylonitrile or acrylates was examined The reaction gave β-alkoxy derivatives with isolated yields of 5-79%. PPh3 is cheaper and more stable than those trialkylphosphines previously used for the similar reactions, and the products can be easily separated from the reaction mixture via distillation This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Reference of 763-69-9).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Reference of 763-69-9
