The PdTe NPs (hexagonal) and nanorods (first example) have been synthesized for the first time from single source precursors (SSPs), [Pd(L1)Cl2] (1) and [Pd(L2)Cl]BF4 (2) [L1, 4-bromo-1-[2-(4-methoxyphenyltellanyl)ethyl]-1H-pyrazole; L2, bis-[2-(4-bromopyrazol-1-yl)ethyl]telluride], by their thermolysis in an OA–ODE mixture (1:1) and TOP respectively. The composition of the PdTe phase does not ...
While thermolysis of the macrobicyclic triene lactone 12 did not produce the expected bicyclic transannular Diels-Alder (BTADA) product 13, heating the corresponding ether 18 to 110 °C for 4 h afforded a quantitative yield of the desired cycloadduct 19, which could be easily reduced to the perhydrophenanthrene, an ABC ring analogue of fusidic acid 1. Theoretical calculations with hybrid density...
The synthesis of the tert-butyl-substituted arsanylborane tBuAsHBH2 ? NMe3 is reported. Its reactivity towards main group Lewis acids and transition metal complexes, yielding various coordination products, discussed. Furthermore, it used as starting material in catenation oligomerization processes, leading to cationic catena compounds well neutral oligomers obtained by thermolysis.
A relatively new entrant to the class of high energy materials, viz., 1,3,5-trinitro-5-methyl-hexahydropyrimidine (MTNP) has been synthesized during this work by nitration of 1,3-di-tert-butyl-5-nitro-5-methyl hexahydropyrimidine with fuming nitric acid. The synthesized molecule (MTNP) has been characterized by elemental analysis, IR, H and C NMR spectroscopy. TG of the compound showed two-step...
