Tris(2,6-diisopropylphenolato)titanium(IV) dihydridodiorganylborates: Synthesis and structures

The reactions of tris(2,6-diisopropylphenolato)titanium(IV) chloride with alkali-metal dihydridodiorganylborates M(H2BR2) (M = Li, K; R = Me, C6H11, CMe3; BR2 = BC5H10, BC8H14) led to the corresponding titanium dihydridodiorganylborates. However, in almost all cases byproducts such as (2,6-diisopropylphenolato)diorganylboranes, triorganylboranes, diorganylboranes, diborane and tetrakis(2,6- diisopropylphenolato)titanium(IV) were also generated. (2,6-iPr 2C6H3O)3Ti(H2BR 2) compounds also resulted from the interaction of methyltris(2,6-diisopropylphenolato)titanium, for example, with catecholborane. In addition to the formation of tris(2,6-diisopropylphenolato) catecholboratotitanium(IV), B-methylcatecholborane was also formed The reaction of potassium dihydro-9-cyclooctylborate with 2,6-bis(2,2-di-tert-butyl-2- hydroxyethyl)pyridinetitanium dichloride (LTiCl2) led to the complex LTi(H2BC8H14)2. This compound showed no agostic C-H···Ti interaction in contrast to (2,6-iPr2C6H3O)3TiH 2BC8H14 and the corresponding titanium dihydridobis(cyclohexyl)borate.

Thermal decomposition of B-N-H compounds investigated by using combined thermoanalytical methods

The thermal decomposition of borazane BH3NH3 in the temperature range up to 500 K has been studied by differential scanning calorimetry (DSC) and thermogravimetry (TG) combined with the FRIR spectroscopic and mass spectrometric analysis of the gas phase. Above 340 K borazane is decomposed in stages as the temperature is increased, The exothermic decomposition is accompanied by the release of approximately 2.2 mol H2/mol BH3NH3. This corresponds to a remarkable hydrogen storage density of 14.3 mass% related to the mass of borazane. In the gas phase above the solid decomposition residue monomeric aminoborane (BH2NH2), borazine (BHNH)3, which is the boron-nitrogen analog of benzene, and traces of diborane B2H6 were found beside hydrogen. The release of significant quantities of borazine was observed only at temperatures above 400 K.
