Abstract: Tetraphenylstibonium hydroxide (Ph4SbOH) acted as a profitable base to effect the synthesis of β-lactams from haloamides. In most cases, acrylamides which were serious by-products in other studies formed in poor yields. Cyclic carbamates were also prepared under the same conditions from the corresponding halocarbamates.
