AbstractA one‐pot, two‐step catalytic protocol for the preparation of cinnamyl ethers from simple and readily available aryl halides, phenols and allyl chloride is reported for the first time. This simple and highly efficient palladium nanoparticles catalytic system shows good regio‐ and stereoselectivities and affords the desired products in good to high yields (49–85%) from aryl iodides. Furthermore, less reactive aryl bromides can also give the cinnamyl ethers in moderate yields (24–72%).magnified image
Palladium-catalyzed Mizoroki–Heck reaction of allyl aryl ethers with aryliodides gave aryl cinnamyl ethers using a catalytic amount of Pd(OAc)2 in DMF at 50 °C with phosphine-free hydrazone as a ligand in good yields.
Synthesis of primaryalcohols from terminalalkenes is an important process in both bulk and fine chemical syntheses. Herein, a homogeneous Pd‐complex‐catalyzed transformation of terminalalkenes into primaryallylicalcohols, by using 5 mol % [Pd(PPh3)4] as a catalyst, and H2O, CO2, and quinone derivatives as reagents, is reported. When alcohols were used instead of H2O, allylic ethers were obtained
