In 2002, Balema and Pecharsky explored the mechanochemical generation of phosphonium ylides under a helium atmosphere using K₂CO₃ as a base. However, their study was limited, focusing on only three phosphonium salts reacted with three aromatic aldehydes. This investigation presented the exclusive example to date of a solvent-free methenylation reaction using a trimethylphenylphosphonium salt. Notably, employing 2-naphthyl aldehyde as a substrate, they obtained the respective vinyl derivative in a 73% yield after an extensive milling time of 20 hours. These findings led us to hypothesize that a Wittig reaction using non-stabilized phosphonium ylides under ball milling conditions is feasible. However, a general and broadly applicable protocol for a solvent-free mechanochemical Wittig reaction using non-stabilized phosphonium ylides and a diverse set of carbonyl compounds has not yet been established. This gap in the literature prompted us to further investigate conditions for fast and high-yielding mechanochemically driven aldehyde-to-olefin conversions. Our newly presented method is unprecedented and outstanding in terms of ease of reaction setup and reaction time, representing a significant advancement in the field of mechanochemical synthesis.
