Direct syn addition of two silicon atoms to a C≡C triple bond by Si-Si activation: access to reactive disilytated olefins

Résumé

A catalytic intramolecular silapalladation of alkynes affords, in good yields and stereoselectively, syn‐disilylated heterocycles of different chemical structure and size. When applied to silylethers, this reaction leads to vinylic silanols that undergo a rhodium‐catalyzed addition to activated olefins, providing the oxa‐Heck or oxa‐Michael products, depending on the reaction conditions.
