Simple preparation of oxygen difluoride in high yield

Infrared Spectroscopic and Theoretical Investigations of Group 13 Oxyfluorides OMF2 and OMF (M=B, Al, Ga, In)

“…Briefly, the 1064 nm fundamental of a Nd:YAG laser (Continuum, Minilite II) with a pulse energy of 50–65 mJ per 10 ns pulse was focused on the elemental group 13 targets through a hole in the cold window. 16/18 OF 2 was synthesized by a known procedure using elemental fluorine and 16/18 OH 2 dispersed in solid NaF [31] . FTIR spectra were recorded on a Bruker Vertex 80v spectrometer for B and Bruker Vertex 70 spectrometer for Al, Ga and In at 0.5 cm −1 resolution in the 4000–430 cm −1 region using an MCT detector.…”

[31] FTIR spectra were recorded on a Bruker Vertex 80v spectrometer for B and Bruker Vertex 70 spectrometer for Al, Ga and In at 0.5 cm À 1 resolution in the 4000-430 cm À 1 region using an MCT detector. The matrix samples were irradiated by an LED light (OSLON 80 4 + PowerStar Circular 4 LED Arrays: λ = 470 � 20 nm, 13 W) or a mercury arc lamp (Osram HQL 250, 175 W) with the outer globe removed.…”

Selective fluorination of m-tyrosine by OF2

“…In order to quantify the relative amounts of 18 F-labeled products that result from the fluorination of aromatic amino acids using OF 2 , attempts were made to synthesize and isolate [ 18 F]OF 2 . The method used in this study involved the direct fluorination of anhydrous KF/ KFÁ2H 2 O in micromolar quantities and is a modification of the gram-scale synthesis reported by Pullen et al [18]. Parameters reported by these workers could not be replicated in our laboratory owing to the scale and reaction conditions required for the production of radiotracers having applications in diagnostic imaging.…”

“…Several synthetic routes have been used to prepare OF 2 , including the reaction of fluorine with aqueous alkali solutions [15], 60% HClO 4 [16], H 5 IO 6 [17], hydrated alkali fluorides [18], or HOF [19]. More recently, Satyamurthy et al [20] reported the www.elsevier.com/locate/fluor Journal of Fluorine Chemistry 129 (2008) [22][23][24][25][26][27] (1) formation of [ 18 F]OF 2 as a reaction byproduct (up to 5% for double shoot and up to 20% for the single shoot irradiation methods) under the high-pressure and high-energy irradiation conditions of a proton cyclotron gas target using the nuclear reaction, 18 O(p, n) 18 F and according to Eqs.…”
