17. As suggested by a referee the assistance of the silicon to stabilize the cationic intermediate would be also described in K, although silicon is known to stabilize positive charges at the beta position through hyperconjugation. However, the intermediate K would explain the selective desilylation in our mechanism. (Formula Presented)
