Abstract
- Utilizing the W(CO)5 group as a promoter, we have established a straightforward pathway for the conversion of simple 1-alkyl-1,2-diphospholes to P,P-bidentate caged phosphines via [4+2] cycloaddition reactions. Furthermore, during the course of our investigation, we have observed a rare instance of isomerization, wherein the W(CO)5 migrates between the two phosphorus atoms in pentacarbonyl(1-alkyl-1,2-diphosphole)tungsten(0). This intriguing phenomenon has been thoroughly investigated using variable-temperature 31P NMR spectroscopy. [ABSTRACT FROM AUTHOR]
