Boron nitride thin fibres obtained from a new copolymer borazine-tri(methylamino)borazine precursor

Boron nitride thin fibres have been obtained using the melt drawn technique from a new molecular precursor prepared by reacting borazine (HBNH)3 with trimethylamino-borazine (CH3NHBNH)3, (MAB). Borazine reacted very slowly

Construction of activated carbon-supported B3N3doped carbon as metal-free catalyst for dehydrochlorination of 1,2-dichloroethane to produce vinyl chloride

Dehydrochlorination of 1,2-dichloroethane (1,2-DCE) is an important oil-based way for the industrial production of vinyl chloride monomer (VCM), but has proved to be plagued by a high operating temperature and low efficiency. Therefore, environmentally friendly and metal-free catalysts are in high demand for green chemical processes. In view of the stronger electronegativity of borazine (B3N3) and convenience of constructing a two-dimensional structure because of the coplanarity of B3N3, the acetenyl group, and the benzene ring, herein, we report a novel controllable B3N3doped activated carbon (B,N-ACs) synthesized using B3N3-containing arylacetylene resin for dehydrochlorination of 1,2-DCE. The result is activated carbon loaded with B3N3-doped carbon nanosheets on the surface due to the B3N3-containing arylacetylene resin grown on the surface of activated carbons. The B,N-ACs deliver excellent catalytic performance, with a 1,2-DCE conversion of ～92.0% and VCM selectivity over 99.9% at 250 °C, significantly higher than that of the current catalysts in the industry. The results further verified that pyridinic-N and the internal B3N3play significant roles in this catalysis. The new green, metal-free B,N-ACs with excellent catalytic efficiency make it a promising catalyst for dehydrochlorination of 1,2-DCE to produce VCM.

Inorganic Triphenylphosphine

A completely inorganic version of one of the most famous organophosphorus compounds, triphenylphosphine, has been prepared. A comparison of the crystal structures of inorganic triphenylphosphine, PBaz3 (where Baz=B3H2N3H3) and PPh3 shows that they have superficial similarities and furthermore, the Lewis basicities of the two compounds are remarkably similar. However, their oxygenation and hydrolysis reactions are starkly different. PBaz3 reacts quantitatively with water to give PH3 and with the oxidizing agent ONMe3 to give the triply-O-inserted product P(OBaz)3, an inorganic version of triphenyl phosphite; a corresponding transformation with PPh3 is inconceivable. Thermodynamically, what drives these striking differences in the chemistry of PBaz3 and PPh3 is the great strength of the B?O bond.

Micrometric BN powders used as catalyst support: Influence of the precursor on the properties of the BN ceramic

Thin powders and foams of boron nitride have been prepared from molecular precursors for use as noble metal supports in the catalytic conversion of methane. Different precursors originating from borazines have been tested. The best results were obtained using a precursor derived from trichloroborazine (TCB) which, after reacting with ammonia at room temperature and then thermolyzing up to 1800°C, led to BN powders with a specific area of more than 300m2g-1 and a micrometric spherical texture. Comparable results were obtained using polyborazylene under similar conditions. Aminoborazine-derived precursors did not yield such high specific area ceramics but the BN microstructure resembled a foam with a crystallized skin and amorphous internal part. These differences were related to the chemical mechanism of the conversion of the precursor into BN. Polyhaloborazines and polyborazines yielded BN through gas-solid reactions whereas aminoborazine polymers could be kept waxy up to high temperatures, which favored the glassy foam. Catalysts composed of BN support and platinum have been prepared using two routes: from a mixture of precursor or by impregnation of a BN powder leading to very different catalysts.
