Abstract:
P-Stereogenic phosphonothioates and phosphonoselenoates were readily prepared utilizing RP-menthyl phenylphosphite 1 by two methods. The first method used elemental sulfur or selenium to react with 1, followed by alkylation of the intermediates with alkyl halides. The second used 1 to react with disulfide or diselenide. Both methods stereospecifically produced the title compounds in nearly quantitative yields under mild conditions. Stereospecific chalcogenation of the phosphoryl was proposed as the key step in these reactions.

A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...
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...

SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...
