New
saturated abnormal N-heterocyclic carbene complexes of gold(I) have
been prepared by a 1,3-dipolar cycloaddition of an in situ generated
azomethine ylide with an isocyanogold(I) choride. A series of different
substituents on the nitrogen atom of the 1,3-dipole are tolerated
without problem. Substitutents on a carbon atom of the 1,3-dipole
are problematic in the case of the isocyanogold(I) chlorides; only
low yields are obtained. However, the corresponding isocyanogold(I)
iodide shows good reactivity, and these abnormal N-heterocyclic carbenes
bear the substituent in a position α to the carbene carbon,
as proven by a crystal structure analysis of one of the products.
Some of the new saturated abnormal N-heterocyclic carbene complexes
were then tested in the gold-catalyzed phenol synthesis; moderate
turnover numbers of 252–380 could be reached.
