- New Phosphonium Ylides by Functionalization of Triphenylphosphoranylideneacetamide
-
Triphenylphosphoranylideneacetamide undergoes Michael reactions with several acceptors, giving rise, apart from the normal Michael adducts, to the formation of different products like glutarimide ylides and stabilized iminophosphoranes.Wittig reactions with these new ylides lead to a variety of α,β-unsaturated carbonyl compounds. Key Words: Stabilized phosphonium ylides, Wittig reaction, Michael reaction, Glutarimides.

- 2-Substituted Glutarimides via Preformed Wittig Reagents
-
Triphenylphosphoranylideneacetamide (1) reacts with some Michael-acceptors to give crystalline 2-triphenylphosphoranylidene glutarimides.The Wittig reaction of 2 with several aldehydes in refluxing 1,2-dichloroethane affords the corresponding 2-alkylidene
