phosphonium Salts, 3. Reductive C-Acylation of Aromatic Aldehydes
The phosphonium salts 5 are synthesized from aldehydes 1, arenecarbonyl chlorides 2 and triphenylphosphane (4), and can then be deprotonated to 7. 7 react as acyl anion equivalents with aromatic aldehydes 9 forming enol esters 10, which are transformed to alkanones 11.The new aldehyde 9->alkanone 11-transformation is characterised as a reductive C-acylation of aromatic aldehydes.
