Intermolecular cycloadditions of conjugated dienes and nitreneprecursors usually produce aziridines. A generally useful method was lacking to directly provide the [4+1] cycloadducts, 3‐pyrrolines. We have realized this transformation by using an uniquely active catalyst, copper(II) 1,1,1,5,5,5‐hexafluoroacetylacetonate ([Cu(hfacac)2]). The method is applicable to a wide array of dienes with good yields

Ruthenium–catalyzedenyne metathesis is a reliable and efficient method for the formation of 1,3-dienes, a common structural motif in synthetic organic chemistry. The development of new transition-metal complexes competent to catalyze enyne metathesis reactions remains an important research area. This report describes the use of ruthenium (IV) dihydride complexes with the general structure RuH2Cl2(PR3)2
