Abstract
The cycloaddition of CO2 to N-alkyl aziridines were efficiently promoted by the convenient TPPH2/TBACl binary catalytic system. The metal-free procedure was effective for the synthesis of differently substituted N-alkyl oxazolidin-2-ones in yields up to 100% and excellent regioselectivities (up to 99%). The mechanism of the reaction was proposed on the basis of a DFT study which indicated the formation of an adduct between TPPH2 and TBACl as the effective catalytic active speciesFile | Dimensione | Formato | |
