Description

Tert-Butyl (triphenylphosphoranylidene)acetate is a tert-butyl substituted tricyclic compound, with a tetraponerine skeleton. It is synthesized from the reaction of acetyl chloride and triphenylphosphoranylidene dichloride in the presence of an amine such as piperidine or 1,4-diazabicyclo[2.2.2]octane (DABCO). The tert-butyl group acts as an electron donor and helps to stabilize the carbocation intermediate. Tert-Butyl (triphenylphosphoranylidene)acetate can be used as a reagent in the synthesis of various secondary amides and tertiary amines, as well as olefination reactions. This compound has been shown to undergo β-unsaturated esterification reactions with α,β-unsaturated carboxylic acids in the presence of aluminum
