摘要

Cyclopropylidenation of α-keto-or α-formyl acetals by Witting reaction with cyclopropylidenetriphenyl-phosphorane leads to α cyclopropylidene-acetals, easily deacetalized by moist silicagel into the corresponding α-cyclopropylidene-ketone and α- cyclopropylidene-aldehydes. The conversion of the latter to the former is also easily carried out by reaction with Grignard reagents followed by oxidation with active manganese ...
