A novel and efficient catalytic epoxidation of olefins with adducts derived from methyltrioxorhenium and chiral aliphatic amines
Abstract.
Nitrogen-based adducts derived from methyltrioxorhenium(VII) and chiral aliphatic amines have been
synthesized and applied to the efficient catalytic epoxidation of olefins with urea hydrogen peroxide
complex as the primary oxidant. These complexes retain their catalytic activity when microencapsulated
in polystyrene. A moderate steroinduction was obtained in the epoxidation of prochiral olefins
with complexes between methyltrioxorhenium and chiral trans-1,2-cyclohexyldiamine. The values of
steroinduction were found to increase after the microencapsulation process.
