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

Matrix isolation and spectroscopic characterization of perfluorinated ortho- and meta-Benzyne

The matrix isolation and spectroscopic characterization of two C6F4 isomers, the perfluorinated o-benzyne 4 and the m-benzyne 5, is reported. UV photolysis of tetrafluorophthalic anhydride 6 in solid argon at 10 K results in the formation of CO, CO2, and 1,2-didehydro-3,4,5,6-tetrafluorobenzene (4) in a clean reaction. On subsequent 350 nm irradiation 4 is carbonylated to give the cyclopropenone 7. 1,3-Didehydro-2,4,5,6-tetrafluorobenzene (5) was synthesized by UV irradiation of 1,3-diiodo-2,4,5,6-tetrafluorobenzene (8) via 2,3,4,6-tetrafluoro-5-iodophenylradical 9. Photolysis of 8 in solid neon at 3 K produces good yields of both radical 9 and benzyne 5, while in argon at 10 K no reaction is observed. Thus, the photochemistry in neon at extremely low temperature markedly differs from the photochemistry in argon. The formation of 5 from 8 via 9 is reversible, and annealing the neon matrix at 8 K leads back to the starting material 8. The benzynes 4 and 5 and the radical 9 were characterized by comparison of their matrix IR spectra with density functional theory (DFT) calculations.

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.
