Photosynthesis of dioxygen difluoride

Polyfluorides and Neat Fluorine as Host Material in Matrix‐Isolation Experiments

“…Another approach is to convert oxygen impurities of elemental fluorine by UV photolysis into OF 2 or with SbF 5 into O 2 SbF 6 , which are both easier to remove 18. 19 This photolysis also removes traces of N 2 as NF 3 .…”

Diastereomeric selective formation of a linear diphosphazane: meso-iso-PrN[PhP(iso-PrNH)]2

“…/-PrN[PhP(y-PrNH)]2Mo(CO)4 (14). To (nor)Mo(CO)4 (1.5 mmol) in toluene was added meso-6 (1.1 mmol) in toluene dropwise at room temperature under N2.…”

“…31P NMR spectral analysis of the filtrate showed only a singlet resonance at 90.3 due to 14. Recrystallization of the product from toluene yielded pure 14 (mp 181-184 °C; yield >90%). Anal.…”
