A previously unreported 1,5-diazacyclooctane-palladium(II) complex was synthesized using bis[N,N′-(2-indanolyl)]-1,5-diazacyclooctane, which was readily prepared via a novel [4+4] homocyclization of the unsaturated imine intermediate generated from acrolein and 1-amino-2-indanol. Interestingly, the 1,5-diazacyclooctane-palladium(II) complex self-assembled to form palladium nanoparticles. This approach
We have developed a sulfur‐modified, gold‐supported palladium material (SAuPd) with palladium, Pd, nanoparticles on its surface; it is a recyclable, low‐leaching Pd catalyst. Here we report, using SAuPd, the first example of Pd nanoparticle‐catalyzed, unactivated C(sp3)Hbondfunctionalization of amides, using 8‐aminoquinoline as a directing group, to yield ethynylated products. The low leaching properties
