Abstract Organic selenium, tellurium and sulfur compounds have been studied due to their pharmacological properties. For instance, the β-aryl-chalcogenium azide compounds have demonstrated antitumoral action in vitro. However, yet no pharmacological

A series of thio and selenoesters were efficiently obtained employing stable diorganyl chalcogenides, acyl chlorides, and In as reducing agent in BMIM·PF6. Recycling of the ionic liquid was also performed, which was reused three times.

Selenium and bromine were refluxed in methanol and stirred with ethylenethiourea to give yellow crystals of [(Se-ettu)2]Br2 (ettu = ethylenethiourea). The first reported 1,2-diselenonium dication stabilized by sulfur atoms is air unstable and yields
