It therefore seems possible that the reaction mechanism is different from what has been previously been suggested. At the highest level of theory, the reaction enthalpy at absolute zero is found to be + 3.1 kcal/mol, in excellent agreement with experiment.J.M.L....

5α-Cholest-8(14)-en-7-one (II) was prepared by a route known to produce authentic steroidal Δ8(14)-7-ketones, and the Δ8(9)-7-ketone (I) was obtained from a side product of this reaction. On the basis of chemical and spectroscopic evidence, it was shown that these samples ar...
Methods for the synthesis of chemical compounds having PDE-IV inhibitory activity Disclosed is a process for the preparation of a compound of Formula IV having the structure: ##STR1## wherein R.sub.6 is N(R.sub. 6a) (R.sub.6b); R.sub.3 represents a C.sub.2-8, alkyl which is ...
A Lesar,AM Kosmas 摘要: The singlet potential energy surface for the CF3S + NO2 reaction has been theoretically investigated using the B3LYP/6-311+G(3df) level of theory. The geometries, vibrational frequencies, and zero-point energies of all stationary points involved in the title reaction ...

3.2.3 Dark zone burning mechanism The complex reaction of CH2O with NO2 provides a source of exothermicity that is relatively low compared to subsequent reactions but important to the overall decomposition of both HMX and PETN [32]. We use a simplified mechanism based on a series of experiment...
We first considered the E-R mechanism on the Co3O4 (110) surface. The first element reaction is the contact of O2 with HCHO to form CH2O2 and an O atom. If gaseous O2 is contacted with HCHO pre-adsorbed on the surface, there will be no conversion into CH2O2 and O due to the la...
Photoredox nickel catalysis has emerged as a powerful strategy for cross-coupling reactions. Although the involvement of paramagnetic Ni(I)/Ni(III) species as active intermediates in the catalytic cycle has been proposed, a thorough spectroscopic investi
The role of this histidine has been proposed to include the interaction with the aspartate of the catalytic triad, specifically in characterizing the hydrogen bond between the two. It has been proposed that the reaction could use a double-proton transfer mechanism in a “charge-relay” (Fig.S1...
