The title compound, C(18)H(24), was the main product of thermolysis of noradamantene dimer (hepta-cyclo-[9.3.1.1(2,6).1(4,8).1(9,13).0(1,9).0(2,8)]octa-deca-ne). The crystal structure was determined to prove that the thermolysis product of noradamantene dimer is favored by stretch release due to ring opening of the four-membered ring. The bond length of the quaternary C atoms of the starting ma...
Syn sulfoxide elimination was carried out under continuous-flow conditions in a mesofluidic thermolysis reactor. The design of the reactor enabled accurate control of reaction time and conditions, affording a convenient scale-independent procedure for the production of N,C-protected vinylglycine derivatives. Thermolysis at 270 °C under 1000 psi of pressure in superheated toluene enabled typical...
BACKGROUND AND OBJECTIVES Hyperhidrosis is a condition that affects a large percentage of the population and has a significant impact on peoples' lives. This report presents a technical overview of a new noninvasive, microwave-based device for creating thermolysis of sweat glands. The fundamental principles of operation of the device are presented, as well as the design and optimization of the ...
On thermolysis appropriately substituted N-silyloxy-N-allyl enamines undergo smooth 3,3-sigmatropic rearrangments to the corresponding N-silyloxy imino ethers.
A series of lanthanide oxide microspheres and hollow spheres have been fabricated by thermolysis of corresponding lanthanide coordination compounds formed via bottom-up self-assembly.
Two different reaction pathways in the photooxygenation of 9,10-diarylanthracenes are identified, with strong evidence for polar (forward, singlet oxygen addition) and radical (backward, thermolysis) intermediates.
Abstract The effect of structure 25 aromatic compounds on the morphology carbon formed from them during heating to a temperature 970°C in an inert atmosphere is studied. specific surface area determined for number products via nitrogen adsorption (28–48 m 2 /g). Several are shown form without melting stage. X-ray phase analysis nevertheless confirms formation just amorphous all cases, and negli...
In several accidents (fires, explosions) involving electrical systems containing polychlorinated biphenyls (PCBs) or benzenes (PCBZs), the formation of polychlorinated tricyclic aromatic compounds such as polychlorinated dibenzofurans (PCDFs), dibenzo-p-dioxins (PCDDs) and biphenylenes (PCBPs) was observed. These findings were not surprising in light of our previous studies on the formation of ...
Porous organic materials have received increasing attention due to their potential applications, such as gas storage, separation, and catalysis. In this work we present a series of aromatic, polyazide-containing building blocks that enable the formation new class amorphous porous materials. The azide precursors are obtained in moderate good yields following an easy synthesis procedure. By therm...
