What is Cp2Mg?
Cp2Mg SSG is a magnesium precursor (Select Semiconductor Grade) for the deposition of compound semiconductors and commonly applied as dopant in GaN-based material systems.
Is Cp a pi donor?
In terms of its ability to stabilize oxidation states, Cp is comfortable with both low and high oxidation states of the metal (unlike many pi-acid ligands like CO which are only found for low oxidation states). In general Cp is a good sigma- and pi- donor, but a poor pi-acceptor.
What is metallocene polymer?
Metallocenes are very effective metal catalyst. They consist of minute particles of positively charged metal ions sandwiched between two cyclopentadienyl anions, which have five atoms per ring.
What type of ligand is PPh3?
Yes, as per the crystal field theory and the spectrochemical series, the PPh3 group can be categorized as a strong field ligand since it has the ability to produce strong splitting.
What is the best example of metallocene?
The most famous example is ferrocenium, [Fe(C 5H 5) 2]+, the blue iron(III) complex derived from oxidation of orange iron(II) ferrocene (few metallocene anions are known).
What is PPh3 used for?
Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C6H5)3 and often abbreviated to PPh3 or Ph3P. It is widely used in the synthesis of organic and organometallic compounds. PPh3 exists as relatively air stable, colorless crystals at room temperature.
Is PPh3 a pi acceptor?
The energy of the σ* orbitals is lower for phosphines with electronegative substituents, and for this reason phosphorus trifluoride is a particularly good π-acceptor.
Why is PPh3 a good ligand?
Which metals are used in metallocene catalyst?
Using a metal salt and cyclopentadienyl reagents It is most easily obtained by the reaction of molten sodium and dicyclopentadiene.

Was ist das CCP von CP/a?
Das CCP von CP/A ist ziemlich sicher ursprünglich aus einem reassemblierten CP/M-2.2-CCP entstanden; wurde aber konsequent auf Z80-Befehle umgearbeitet und vielfach verändert und erweitert. […] Das CP/A-BDOS wurde im Prinzip komplett und fast 1:1 aus dem DR-BDOS abgekupfert […]
