The use of organotellurium heterocycles as precursors for novel organometallic compounds
The reactions of group 16 heterocycles with organometallic reagents are described. Thiophenes have been used as models for organic sulfur in coal and their reactivity towards triiron dodecacarbonyl has been investigated. Reaction of unsubstituted thiophene with Fe3(CO)12 results in desulfurisation …
