We were pleased to find that our optimized protocols were compatible with a wide array of allylic silanol substrates. Alkyl chains of diverse lengths and branching patterns (Scheme 3, Entries 1, 7, and 8), cyclic hydrocarbons (Scheme 3, Entries 2 and 4), aliphatic ethers (Scheme 3, Entries 3 and 6), aromatic halogens (Scheme 3, Entry 5), aromatic ethers (Scheme 3, Entry 5), and aromatic CF3 groups (Scheme 3, Entry 9) were all tolerated. For substrates not shown here, we recommend empirically testing both protocols A and B for best results.
