The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate(SMILESS: CC1=C([N+]2=CN(C3=C(C)C=C(C)C=C3C)C=C2)C(C)=CC(C)=C1.F[B-](F)(F)F,cas:286014-53-7) is researched.COA of Formula: C8H9ClN2OS. The article 《Nickel-catalyzed amination of aryl chlorides using a dihydroimidazoline carbene ligand》 in relation to this compound, is published in Tetrahedron Letters. Let’s take a look at the latest research on this compound (cas:286014-53-7).
A new arylamination protocol was developed using a catalyst combination prepared from Ni(acac)2 associated to a sterically hindered dihydroimidazoline carbene ligand. A high efficiency was attained using, in most cases, only 2 mol% Ni/carbene clusters.
