The Chemistry of Sulfur Tetrafluoride. II. The Fluorination of Organic Carbonyl Compounds¹

The chemistry of chromium (VI) and chromium (V) oxide fluorides

“…This mechanism is analagous to the one proposed for the reaction of SF 4 11ith carbonyl groups (38) .…”

Sugar Esters: Iii. New Reagent for Deoxyhalo Sugar Preparation

“…'I'he degree of coplanarity achieved by a benzene ring and its conjugated substituents has been the subject of close scrutiny in recent years, and X-ray crystallographic results suggest t h a t complete coplanarity is rarely achieved in the crystalline state (1)(2)(3)(4)(5). Noncoplanarity inlplics loss of resonance energy (B), \~h i c h is presumably offset by the energy gain froin relief of steric colllpression or improved molecular paclting in the crystal.…”

Synthesis and modification of octafluoro[2.2]paracyclophane (parylene AF4)

“…Terephthalaldehyde 14 is fluorinated using sulphur tetrafluoride to yield p-bis-difluoromethyl benzene 5 16 and this is subsequently chlorinated (or brominated if desired) by a photo halogenation process to yield the desired precursor 3.…”
