... Aside from a lack of selectivity, LAH reacts violently with water and other hydroxylic compounds, and reductions using this reagent must be carried out under non‐protic, anhydrous conditions. This not only limits the solvents with which LAH can be used, but it presents greater challenges in th ...

... equivalent of the nucleophile. Addition of excess MeMgBr (5 equivalents, 1.5 h, rt.) to 1a generates a 2/1 mixture of bis- and mono-addition products whereas addition of excess iPrMgBr gives only the monoaddition product. This is presumably due to steric factors (quaternary center adjacent to the re ...
