Lewis acid triggered reactivity of a lewis base stabilized scandium-terminal imido complex: C-H bond activation, cycloaddition, and dehydrofluorination

A stable scandium-terminal imido complex is activated by borane to form an unsaturated terminal imido complex by removing the coordinated Lewis base, 4-(dimethylamino)pyridine, from the metal center. The ensuing terminal imido intermediate can exist as a

Extent of the Displacement Route in the Reactions of Fluorine Atoms with Ethylene. Vinyl Chloride, and Vinyl Bromide

The chemical branching of three fluorine-atom reactions, those with C2H4, C2H3Cl, and C2H3Br, was studied in real-time experiments using a tubular reactor coupled to a photoionization mass spectrometer.The fluorine atoms were generated by the CO2-laser-induced secondary photolysis of C6F5Cl which also appears to produce tetrafluorobenzene (c-C6F4).The measured fractional extents that the three reactions studied proceed by a displacement route at 295 K (to yield C2H3F + X) are 0.65 (+/-0.06), 0.72 (+/-0.14), and 0.72(+/-0.14) for C2H4, C2H3Cl, and C2H3Br, respectively.
