- •
MnO3L addition to ketenes prefer the concerted [3+2]C
- •
[2+2] addition possible only in the reaction of MnO3–OCH3 with dimethyl ketene.
- •
Reactions involving an increase in oxidation state of metal have higher activation barriers.
- •
Low activation barriers are obtained when the substituent on the ketene is electron-donating.
