On the example of the carboranyl derivatives of mercury it was shown that the essence of nucleophilic catalysis in reactions of the S E 1-N type consists in the one-electron reduction of the metal-carbon bond with the formation of the carbanion. Under anionic catalysis conditions organomercury...
Nucleophilic Addition to Carbonyl Compounds. Competition Between Hard (Amine) and Soft (Phosphite) Nucleophile In the reaction mixture of carbonyl compound, amine and diethyl phosphite several different reactions are observed. The formation of aminophosphonate (Kaba... R Gancarz,I Gancarz,A Masiowska...
Two synthetic routes were utilized: (i) using the chloro-precursor 1a in nucleophilic substitution reactions with a variety of anionic and neutral nucleophiles to give compounds 1b– 1f and (ii) reaction of spermine with the appropriate di-gem tetrasubstituted cyclophosphazene to give compounds 1g ...
great example of hydrolysis.Hydrolysisis the process of using water to break down a molecule into two parts. The prefix 'hydro-' means water, while the suffix '-lysis' means to break down. Hence, if you see the word hydrolysis you can automatically think of the term, 'reaction with ...
ADP-ribose 1″-phosphate phosphatase catalyzes the following reaction. It is an equilibrium reaction that lies to the right and the amount of phosphate released is proportional to the amount of the substrate added. In ADP ribose the ring is predominantly in open form favored in alkaline ...

Diels--Alder reactionNucleophilic allylic substitutionChiral N , N -coordinating ligands have been particularly synthesized for their use as metal chelates catalyzing asymmetric C-C bond formations. Bis(oxazoline) structures have been the most studied, probably due to their straightforward synthesis...
