A stable adduct of Cul with Bu4NI, soluble in organic solvents, has been identified as an effective catalyst for copper-catalyzed C-N and C-O couplings. In addition, stable nonhygroscopic salts of some high performance ligands (diamine MsOH salts/CuX and copper(II) diketonates) were shown to be of similar and sometimes greater reactivity compared to the literature reagents for these couplings. Furthermore, these more robust conditions result in more reproducible results.

Metal−free catalysis of the reductive amination of aldehydes using a phosphonium−doped porous aromatic framework
The development of metal−free, recyclable, and efficient catalysts for the reductive amination of aldehydes is extremely promising for the preparation of amines in synthetic organic chemistry. In this study, OTf@PAF−180, a porous aromatic framework (PAF) containing rich Lewis acidic phosphonium centers and triflate (−OTf) counter anions, was prepared via Yamamoto−type Ullmann cross−coupling of tri
