Amides have been successfully used as precursors of imidoyl radicals for radical cyclisation. The amides have been converted to imidoyl selanides via reaction with phosgene to yield imidoyl chlorides followed by reaction with potassium phenylselanide. Imidoyl selanides were reacted with tributyltin hydride (Bu 3 SnH) as the radical mediator with triethylborane or AIBN as initiators to yield...
A new, faster and cleaner method for the synthesis of heterobimetallic alkyne complexes is reported. Higher yields than previously obtained are achieved and in some cases moderate stereoselectivity has also been observed.
