Copper-promoted iodovinylation of amides: synthesis of β-functionalized enamides
We studied the addition of nitrogen radicals to ynol ethers in order to form β-functionalized enamides. Poor yields are reported. On the other hand, we observed that copper coupling between 1,2-diiodoethene and various amides leads to β-functionalized enamides in high yields with complete stereocontrol.

Determination of quantum yield for the photolysis of aqueous solution of chloramine-B
Photolysis of aqueous solution of chloramine-B (0.01-0.0002 mol dm-3) is studied with a UV light source and the products have been identified. A suitable photolytic mechanism is suggested based on the observed results. The photolytic decomposition obeys first order kinetics. Quantum yield for the photolysis of chloramine-B is reported.
