The purpose of the project was to investigate the reactivity of selected allyl acetates for substitution with phosphorus nucleophiles or phosphorus-containing carboanions. Triethyl phosphite, triethyl phosphonoacetate and tetraethyl methylenedi- phosphonate were used for the reaction. The products are α,β-unsaturated esters containing one or more phosphonate moieties for which hydrolysis to the acidic form was performed using bromotrimethylsilane. As a result, we obtained a variety of multifunctional compounds. Their structures were characterized with spectroscopic methods. For policarboxylic compounds, we encountered issues with purification of the obtained products.
Celem projektu było zbadanie reaktywności wybranych octanów allilowych w substytucji nukleofilami fosforowymi lub karboanionami zawierającymi atom fosforu. W reakcji zastosowano fosforyn trietylowy, fosfonooctan trietylowy oraz metyleno- bisfosfonian tetraetylowy. Produktami były α,β-nienasycone estry zawierające grupę lub grupy fosfonianowe, dla których następnie przeprowadzono hydrolizę do form kwasowych z użyciem bromotrimetylosilanu. W wyniku tego otrzymano szereg związków wielofunkcyjnych, których struktury poddano charakterystyce technikami spektroskopowymi. W przypadku związków polikarboksylowych napotkano trudności z wydzieleniem oczekiwanych produktów.
