Bi(CF3)3/Cu(OCOCH3)2 — a new system for the synthesis of 2-trifluoromethylcycloalkan-1-ones, trifluoromethylanilines and phenyl(trifluoromethyl)sulfane
Bi(CF3)3 reacts in the presence of equimolar amounts of Cu(OCOCH3)2 and 1-morpholinocyclopentene to give 1-morpholino-2-trifluoromethylcyclopentene in 83% yield. This compound as well as intermediately formed 1-morpholino-2-trifluoromethylcyclohexene can easily be converted into the corresponding cycloketones (78 and 41% yield) using the Swarts procedure. In absence of a copper(II) source, no reactions

reaction of arylhalides with secondary amines in the presence of silylamide base and tri-o-tolyphopshine palladium complexes gives arylamine products. This process provides a convenient method for performing these hetero-cross coupling reactions without the necessity for forming tin amides and disposing of tin halides. This reaction follows from a mechanistic analysis of the coupling reaction with
