Halogen exchange reaction of optically pure halotelluranes

A series of optically pure chlorotelluranes (2a-c) has been prepared by using the 2-exo-hydroxy-10-bornyl group as a chiral ligand. Fluoro, bromo, and iodotelluranes (1,3, and 4) were also prepared by the halogen exchange reaction of 2 in the presence of NaX, AgX, or tetrabutylammonium halide (TBAX) (X = halogen). The retention of the stereochemistry of chiral tellurium atom was observed throughout the reaction. An SN1 pathway was proposed as the mechanism of this halogen exchange reaction.

First synthesis and structure of optically pure Te-chiral-alkoxytelluranes

The first synthesis and isolation of optically pure Te-chiral-alkoxytelluranes 1 and 8 have been developed using the 2-exo-hydroxy-10-bornyl group as a chiral ligand. A distorted trigonal bipyramidal (TBP) structure of 1i with R configuration was confirmed by the X-ray analysis.
