Fluorinating agent

An object of the present invention is to provide a novel substance that has a high reactivity as a fluorinating agent, is effectively used in various fluorination reactions, and is safely handled even in air. As the solution for achieving this object, the present invention provides a complex obtained by reacting bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals in a nonpolar solvent. This complex serves as a fluorinating agent that provides excellent fluorination performance and that is stable in air.

Renewable ketone waxes with unique carbon chain lengths and polarities

The present disclosure provides ketone waxes, methods of forming ketone waxes, and compositions comprising ketone waxes. In at least one embodiment, a ketone wax is provided. The ketone wax includes about 50 wt % or greater C.sub.40-C.sub.90 ketone content; about 50 wt % or greater of the ketone wax has a boiling point of 961 F. or greater; and a paraffins content of less than about 10 wt %, as determined by 2-dimensional gas chromatography. In at least one embodiment, a method for forming a C.sub.40-C.sub.90 ketone wax includes exposing a feed stock to a basic catalyst under conditions suitable for coupling unsaturated carbon chains from the feed to form a composition including a ketone wax, oligomerizing the ketone wax to form a ketone wax having C.sub.40-C.sub.90 ketone wax, and distilling and/or extracting the oligomerized ketone wax to provide a C.sub.40-C.sub.90 ketone wax of the present disclosure.

Polycyclic carbogenic molecules and uses thereof as anti-cancer agents

Disclosed are new polycyclic carbogenic molecules and their methods of synthesis. The new polycyclic carbogenic molecules may be utilized in anti-cancer therapies. In particular, the polycyclic carbogenic molecules may be formulated as pharmaceutical compositions that comprise the small molecules, which compositions may be administered in methods of treating and/or preventing cell proliferative diseases and disorders such as cancer. The new polycyclic carbogenic molecules may be prepared from vinyl- or allyl-substituted cyclohexenone precursors via preparation of a silyl bis-enol ether intermediate.
