PEPPSI-type imidazolylidene Pd complexes having their carbenic ring N-substituted with an aryl ring and a cavity-shaped unit [25,26,27,28-tetrapropyloxycalix[4]aren-5-yl or 6(10),12(16),18(22)-tetramethylenedioxy-2,8,14,20-tetrapentylresorcin[4]aren-5-yl (TPR)] were prepared and assessed in Suzuki-Miyaura cross-couplings. Remarkable efficiency in the coupling of aryl chlorides with sterically hindered arylboronic acids was observed for the carbene ligand having its N atoms (N1, N2) substituted by a mesityl and a TPR group, resp. This good performance possibly arises from strong steric interactions between the pentyl-substituted cavitand unit and the catalytic center, which favors reductive elimination. Two of the imidazolium salts used for complex synthesis were characterized by x-ray diffraction anal. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Quality Control of Bis(2,4,6-trimethylphenyl)iodonium triflate).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.Quality Control of Bis(2,4,6-trimethylphenyl)iodonium triflate
