A turn‐up for the Brook : The relative ease of silyl migration in the aliphatic retro‐Brook rearrangements of α,γ‐disilyloxy organolithium compounds (see scheme) has been revealed for the first time to be [1,2]≪[1,4]. The increasing size of the silyloxy group at the γ position relative to that at the α position induces higher [1,4] selectivity.
