Taking the excellent activity of TMSOTf into account, the structural scope of this hydroboration of aldehydes with 2 a was studied employing aromatic aldehydes a – h with different electronic features (Table 1 ). From these results a clear trend was observed, being the reaction time significantly longer for electron‐poor aldehydes (entries 3 and 4) in comparison with the model substrate 2a (entry 2).
