Ring Opening Reactions of β-Propiolactam in Superacidic Media.
Ontology highlight
ABSTRACT: The reaction of β-propiolactam in the superacidic systems HF/MF5 (M=Sb, As) led to the formation of monoprotonated 3-aminopropanoyl fluoride in the form of [C(O)F(CH2 )2 NH3 ][SbF6 ] and [C(O)F(CH2 )2 NH3 ][AsF6 ]. In the presence of traces of water, the diprotonated species β-alanine [C(OH)2 (CH2 )2 NH3 ][AsF6 ]2 was synthesized for the first time. All salts were characterized by low-temperature infrared and Raman spectroscopy. Additionally, single-crystal X-ray analyses were conducted in the case of [C(O)F(CH2 )2 NH3 ][SbF6 ] and [C(OH)2 (CH2 )2 NH
