The nitrogen-ylide complex 3 reacted with HBF₄ to give in high yield the fluoroborate complex 6 which upon UV irradiation in the presence of O₂ led to the metal-free fluoroborates 7 and 8 fully characterized by X-ray crystallography; deprotonation of 7 in the presence of trace amount of water led instantaneously, upon hydrolysis, to the lactone 11, whereas deprotonation of 8 in the presence of ethanol gave the aminoester 12.
