We review some of the work that we have been doing in the field of elementary reactive processes with interest in atmospheric chemistry and combustion processes. After a brief analysis of the relevant potential energy surfaces, we report dynamics studies of four tetratomic chemical reactions: (1)...
tandem reactionsFour different types of fused arenes, including fluoranthene, indeno[2,1-a]phenalene, (8H)cyclopenta[a]acenaphthylene, and pyridine[a]acenaphthylene, were efficiently constructed through iodine-mediated electrophilic cyclizations of 1,8-dialkynyl naphthalenes in a single step. ...
Energy cannot be produced or destroyed, but can be transferred or change in form.Coupled reactions are subjected to an energy transfer from reactants to products or vice-versa such that the intermediate of the reaction process is common to both sides. So during a two-step process where the ...

One of the main types of compounds among the reported ring systems are the 1,2,3-selenadiazoles. The interest in 1,2,3-selenadiazoles arises from the fact that they undergo a wide variety of reactions with the loss of nitrogen and/or selenium. They are converted to different organoseleniu...

synthases We used 3′ 'rapid amplification of complimentary ends' or RACE reactions to obtain partial transcripts contain- ing the terpene synthase DDxxD motif using the degen- erate 'DDXYDfx' primer and T35VN previously used to successfully isolate terpene synthases from 21 species of Myrtaceae [...
Reagent ions generated in the ionisation region and product ions created through reactions with the reagent ions in the reaction region migrated under the influence of the applied electric field towards an ion-gate. Using a square wave pulse of 1 μs width operating at a frequency of between 10...
