Abstract

Abstract Dialdehydes can give rise, through a Wittig reaction carried out in an anhydrous homogeneous medium, to the corresponding diolefins (1–3). The high reactivity of the ylides generated under these experimental conditions precludes mono olefination which therefore requires the previous protection of one of the aldehyde functions (1–3).
