Thus, the cross-coupling with organozinc compounds (commonly referred to as the Negishi reaction) is a more specialized method; it is, however, indispensable when the combination of high reactivity and maximal tolerance to functionality in the coupling partners is required. Sources for the organo...
Compared with traditional mechanical alloying (MA, i.e. high energy ball milling) processes, this mechanochemistry approach shows the advantages in finer particle size, higher purity of production, faster reactivity speed and different micro-reaction mechanism. A number of ternary intermetallics of Al-...
Compounds, being a subset of molecules, are also represented by molecular formulas, but these formulas specifically indicate a combination of different elements. 15 In conclusion, while both Compounds and Molecules pertain to the makeup of matter, they differ fundamentally. Compounds always involve ...
The latter reaction, also called transamination, implies the cleavage of SiN bonds and may lead to the escape of volatile aminosilanes or oligosilazanes. On the other hand, successive transamination steps lead to the loss of NH3, which lowers the final N/Si ratio and increases the degree of...
