Brominated 1,3-dimethyl-3-phenyl-1-(2-methyl-2-phenylpropyl)-indane and method for preparing the same

A brominated 1,3-dimethyl-3-phenyl-1-(2-methyl-2-phenylpropyl) indane herein disclosed is represented by the following general formula (I): STR1 (wherein x and z each independently represents an integer ranging from 0 to 5, y represents an integer ranging from 0 to 4, provided that x+y+z>1). The compound can be prepared by a method which comprises the step of reacting 1,3-dimethyl-3-phenyl-1-(2-methyl-2-phenylpropyl) indane with a bromination agent. The brominated indane is excellent in flame-resistance, has a high thermal decomposition temperature and never generates brominated dioxine and/or brominated dibenzofuran when burning at a specific temperature. Therefore, the compound is suitably used for imparting flame-resistance to a variety of thermoplastic and thermosetting resins.

Reactions of electrophilic transition metal cations with olefins and small ring compounds. Rearrangements and polymerizations

The reactivity of the cationic, weakly ligated, tranisition metal compounds, (BF4)2 (1); (BF4)2, (M = Ni, 2; Co, 3); (BF4)2, (M = Mo, 4; W, 5), vis-a-vis olefins and strained ring compounds was studied.A number of these species were observed to form a charge-transfer complex with tetra-p-anisylethylene.These compounds were also found to catalyze the skeletal rearrangement and polymerization of appropriately substituted olefins and cyclopropanes.These reactions appear to be initiated by the electrophilic (heterolytic) cleavage of either the ?-bond of the olefin or a strained C-C ?-bond of the small ring compound.

Chemistry of Weakly Solvated Lanthanide-Metal Cations. Synthesis, Characterization, and Catalytic Chemistry of x

The title compound, x, 1, was synthesized by the NOBF4 oxidation of metallic Eu in CH3CN.The interaction of the BF4- ions with the Eu(III) center was established by molecular weight, conductivity, and 11B and 19F NMR spectral measurements. 1 was found to exist as a dimer in CH3CN.In addition, it behaved as a 1:2 electrolyte, indicating the coordination of two of the BF4- ions per Eu(III) ion.However, the conductivity increased when chelating amines were added due to the partial displacement of the coordinated BF4- ions.The 11B and 19F NMR spectra of 1 in CH3CN indicated the presence of two different types of BF4- anions, one of which was isotropically shifted due to interaction with the paramagnetic Eu(III) center.The coordinated BF4- anions could be displaced quantitatively by the addition of 2 equiv of NO3- ions per Eu(III) ion.A degenerate metathesis of the fluorine between the BF3 and the coordinated BF4- ions was observed when BF3 was added to a CH3CN solution of 1. 1 formed a charge-transfer complex with tetra-p-anisylethylene in CH3NO2 but not in CH3CN.In addition, 1 initiated the oligomerization and the polymerization of styrene, α-methylstyrene, and 1,3-cyclohexadiene in CH3NO2.The molecular weights of the polymers obtained increased markedly on lowering the reaction temperature.At room temperature, indan derivatives were obtained from α-methyl- and α-phenylstyrene.The rate of polymerization of styrene was markedly attenuated when CH3CN was used instead of CH3NO2. 1 also initiated the isomerization of quadricyclane and the ring-opening polymerization of 2(10)-pinene and cyclopropylbenzene in CH3NO2.
