Abstract:
Treatment of phosphine substituted beta-diketiminate lithium, Ph2PC[C(Me)N(Dipp)]2LiOEt2 (1) (Dipp = 2,6-iPr2C6H3) with dioxane x GeCl2 resulted in a five-membered N,P chelate complex, Ph2PC[C(Me)N(Dipp)]2GeCl (2). An isomer of 2 CH{[C(CH2PPh2)N(Dipp)][C(Me)N(Dipp)]}GeCl (5) was obtained from the germanium complex L'Ge (L' = CH[C(CH2)N(Dipp)][C(Me)N(Dipp)])Ge (4) and Ph2PCl. In 5 the PPh2 group remains uncoordinated. Both complexes were characterized by X-ray structural analysis and in the case of 5 both enantiomers crystallize in the same unit cell.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

Aldehydes and Ketones to Alkenes: Wittig Reaction Mechanism
The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
