Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:141556-42-5) through the article.
The first cationic and neutral tungsten alkylidyne N-heterocyclic carbene (NHC) complexes bearing one triflate ligand were synthesized and tested for their reactivity in alkyne metathesis. Both types of tungsten alkylidyne complexes display a higher productivity in alkyne metathesis than the analogous neutral tungsten alkylidyne NHC trisalkoxide complexes. Reaction of W( CC6H4OMe)(1,3-bis(1-hydroxy-1,1-trifluoromethylethyl)-imidazol-2-ylidene)Cl (W18) with AgB(ArF)4 (ArF = 3,5-bis(trifluoromethyl)phenyl) resulted in the unexpected formation of, to the best of our knowledge, the first cationic ditungstatetrahedrane W2(1,3-bis(1-hydroxy-1,1-trifluoromethyl-ethyl)-imidazol-2-ylidene)2(MeCN)(μ-((Ar)CC(Ar)))+ (B(ArF)4)- (W19, Ar = C6H4OMe), which suggests bimol. decomposition as a possible decomposition pathway of cationic tungsten alkylidyne NHC complexes. Reaction of the cationic tungsten alkylidyne NHC complex W( CC6H4OMe)(1,3-diisopropylimidazol-2-ylidene)(OC(CF3)2Me)2(NCtBu)+ (B(ArF)4)- (W7) with 1-phenyl-1-propyne allowed for the isolation of a cationic tungstacyclobutadiene W(C3(Ph)(Me)(C6H4OMe))(1,3-diisopropylimidazol-2-ylidene)(OC(CF3)2Me)2(NCtBu)+ (B(ArF)4)- (W20). Its formation strongly supports a cationic active species in the alkyne metathesis with tungsten alkylidyne NHC complexes.
