Reactions of aryl and hetero vicinal tricarbonyl derivatives with aldehyde Schiff bases of the general structure RCH2CHO lead to pyrrolinone derivatives by benzilic acid-related rearrangements, driven, most probably, by iminium ion intermediates.

Acyl phosphoranylidines react with acid chlorides or anhydrides in the presence of bis(trimethylsilyl)acetamide (BSA), or couple directly with carboxylic acids activated by EDCI to give keto phosphoranes 1.
