A sensitive amine-responsive disassembly of self-assembled AuI -CuI double salts was observed and its utilization for the synergistic catalysis was enlightened. Investigation of the disassembly of [Au(NHC)2 ][CuI2 ] revealed the contribution of Cu-assisted ligand exchange of N-heterocyclic carbene (NHC) by amine in [Au(NHC)2 ]+ and the capacity of [CuI2 ]- on the oxidative step.

tetranuclear gold complexes, a structurally unprecedented octanuclear complex with a planar [Au(I) 8 ] core, and pentanuclear [Au(I) 4 M(I) ] (M=Cu, Ag) complexes is presented. The linear [Au(I) 4 ] complex undergoes C-H functionalization of carbonyl compounds under mild reaction conditions. In addition, [Au(I) 4 Ag(I) ] catalyzes the carbonylation of primary amines to form ureas under homogeneous conditions

Adamantyl-containing 1,3-disubstituted ureas, bisureas, and biscarbamates containing different spacers between the ureylene or the carbamate groups and the adamantyl radical were synthesized. Their inhibitory activity against soluble epoxide hydrolases of mammals and humans (sEH, E.C. 3.3.2.10) was studied. The compounds were found to possess high inhibitory activity on the level of 0.8—2.7 nmol L–1. A relationship between the inhibitor structure and its activity was established.
