The present invention provides methods for the thermolysis of lignocellulosic materials, such as wood, cellulose, lignin, and lignocellulose. In specific embodiments, the methods comprise combining the lignocellulosic material with an ionic liquid and subjecting the mixture of the lignocellulosic material and the ionic media to pyrolytic conditions to form a recoverable product, such as a commo...

We report the large-scale synthesis of uniform-sized hexagonal pyramid-shaped ZnO nanocrystals by the thermolysis of Zn-oleate complex, which was prepared from the reaction of inexpensive and environmentally friendly reagents such as zinc chloride and sodium oleate. Under optimized reaction conditions, we were able to synthesize as much as 2.83 g using 300 mL of oleylamine and 90 mL (284 mmol) ...

Thermolysis of a toluene solution containing [Fe2W(CO)10( 3-S)2] (1) and [( -C5H5)W(CO)3(CCPh)] (2), at 80°C yields the mixed metal cluster [Fe2(CO)6( 3-S)2W{( -C5H5)W(CO)3(CCPh)}2] (3). Structure of 3 has been established crystallographically. It consists of a triangular Fe2W unit, each face of which is capped by a sulfido ligand. Each Fe atom bears three carbonyl groups. Two separate molecule...

Small angle x-ray scattering ~SAXS! measurements were performed on nanoporous methyl silsesquioxane films that were generated by the incorporation of a sacrificial polymeric component into the matrix and subsequently removed by thermolysis. The average pore radii ranged from 1 to 5 nm over a porosity range of ;5–50%. The distribution in pore size was relatively broad and increases in breadth wi...

An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl bromide to provide 2-(bromomethyl)oxazoles. The latter compounds are versatile building blocks for nucleophilic displacement reactions as demonstr...

[60]Fullerene-fused pyrazolines 1 were prepared by the reaction of C60 with alky diazoacetates under the solid-state high-speed vibration milling conditions as well as in toluene solution. Pyrazolines 1 were stable in refluxing toluene and its thermolysis process in 1,2-dichlorobenzene was investigated, the decomposition rates and activation energies of pyrazolines 1 were obtained. The current ...

The complexes [Ru(Tai)Cl{=C(H)Ph}(PCy(3))] (4) and [Ru((Ph)Bai)Cl{=C(H)Ph}(PCy(3))] (5) [where Tai = HB(7-azaindolyl)(3) and (Ph)Bai = Ph(H)B(7-azaindolyl)(2)] have been prepared and structurally characterised. The borohydride unit is located in the coordination site trans to the chloride ligand in both complexes. The degree of interaction between the borohydride group and the metal centre was ...

We report the self-assembly of single crystals of single-walled carbon nanotubes (SWCNTs) using thermolysis of nano-patterned precursors. The synthesis of these perfectly ordered, single crystals of SWCNTs results in extended structures with dimension on the micrometer scale. Each crystal is composed of an ordered array of tubes with identical diameters and chirality, although these properties ...

modified form, the Wittig cyclisation chemistry of Woodwardet al.3) and Nayler et al.4) (Scheme 1). The racemic acids (4) were converted in conventional fashion into the corresponding chloromethyl ketones (5), which were then used to alkylate the azetidinone thiol5) (6). Addition of ^-butyl glyoxylate to the derived ketone (7), followed by elaboration of the aminols (8) with thionyl chloride an...

One of the challenges in polymer science has been to prepare large-polymer single crystals. We demonstrate a visible light-triggered quantitative topochemical polymerization reaction based on a conjugated dye molecule. Macroscopic-size, high-quality polymer single crystals are obtained. Polymerization is not limited to single crystals, but can also be achieved in highly concentrated solution or...
