WebThe acid-catalyzed addition of alcohols to alkenes occurs via a mechanism analogous to acid-catalyzed alkene hydration. The reaction occurs in 3 steps: 1) Addition of H+ to the alkene, together with any possible carbocation rearrangements; 2) Addition of the alcohol to the carbocation; 3) Deprotonation to yield the product ether. Web6976 yield. The propellane 10 is produced from the thioester 6 following formation of the et, l]-unsaturated acyl radical intermediate 7 which takes part in a 5-exo trig transannulation via its ~-ketenyl radical counterpart l, leading to 8; the radical 8 then undergoes intramolecular 5-exo dig cyclisation into the ketene electrophore giving rise to 9. how to calculate for carpet https://ardingassociates.com
