Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
In this second chapter, we have grouped the physical and chemical
properties of elemental calcium and calcium cation species as well as their importance
in the human body, especially in the skeleton and cell, as well as their applications in
the chemical, electrical, and biological life fields.
In a nutshell, we describe the history of the organocalcium Ca-Cσ-bond containing
compounds.
Then, we expose the encountered challenges and difficulties in the synthesis of
organocalcium Ca-C containing compounds: before, during and after the
organocalcium preparation and the solutions to overcome these difficulties.
We have grouped the calcium activation methods, the nature of the solvent, the
substrate structure, temperature and the optimal experimental reaction conditions.
