NHC with EWGs for RCM: Ruthenium complexes with two N-heterocyclic carbenes (NHCs), one of them substituted with electron-withdrawing groups (EWGs), are highly efficient (pre) catalysts for the synthesis of tetrasubstituted olefins and trisubstituted olef

Vinyl oxiranes are rearranged to 2,5-dihydrofuran using catalyst (III) or (IV). The 2,5-dihydrofuran can be reduced to tetrahydrofuran. 3,4-Epoxy-l-butene substrate is converted to 2,5-dihydrofuran which in turn is converted to tetrahydrofuran. Substrate
