چکیده

Objectives . Catalytic processes involving norbornene (NBN) and norbornadiene (NBD) offer exceptional opportunities for the synthesis of a wide range hard-to-reach polycyclic hydrocarbons. The problems selectivity manufacturability these reactions are fundamentally important their practical implementation. aim this review is to summarize latest advances in field designing heterogeneous catalysts preparation transformation promising NBN- NBD-derivatives with maintenance strained carbocyclic framework isomerization dimerization compounds. Results Various strategies selection prospects development catalysis syntheses based on NBN NBD derivatives were considered. possibility selective cyclic was shown. factors that affect direction make it possible maintain norbornane structure discussed. Conclusions An analysis current state problem showed at present, technological parameters conversion participation significantly inferior homogeneous systems. In order improve productivity design catalyst regeneration, further investigations required. However, some progress areas has already been made. number processes, not only framework, but also establish ways control regio- stereo-selectivity. cases, use allows process be direct into completely new path, which no analogues

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

the impact of skopos on syntactic features of the target text

the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
