Gratifyingly, using a solvent-free Stahl oxidation protocol by Porcheddu et al. involving catalytic amounts of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO), N-methyl imidazole (NMI), 2,2'-bipyridine (bpy) ligand, and cheap [Cu(CN)4](OTf), we achieved a fully solvent-free, mechanochemical oxidationolefination sequence without intermediate workup (Figure , bottom). The catalytic active species for oxidation was pre-formed for 1 minute at 36 Hz, after which the primary alcohol was added. The oxidation, using air as the oxidant, proceeded at 36 Hz for 15 minutes. As soon as TLC indicated complete oxidation of IV, a pre-formed ylide-created by milling the phosphonium halide and base for one minute-was added as a yellow paste to the aldehyde-containing vessel. The mixture was then milled for one minute, yielding the desired olefin 1 in 74% over two steps. This one-pot protocol is remarkable for its efficiency and simplicity, eliminating the need for solvent and minimize intermediate handling, thus paving the way for greener multi-step syntheses.
