  摘要：

  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

The acetonitrile ligands in complexes 2a–c are labile, as emphasised by the easy formation of Ru(Cp*)(CO)2[Ph2PCH2C(=O)tBu]}[PF6] (3). The keto-phosphane is used as a tool to convert 3 into Ru(Cp*)(CO)[Ph2PCH2C(tBu)=O]}[PF6]

An X-ray structure determination of the complex [Cp*(MeCHCHCH2)(MeCN)RuBr][PF6] disclosed an (endo-trans-MeCHCHCH2) allylic ligand. The structural information obtained from the study of Cp*(allyl)Ru(IV) complexes indicated that electronic effects at the coordinated allylic ligand likely account

  (RuCp*Cl-2)(2), a general entry into Cp*Ru sandwich and half-sandwich chemistry was first used as a precatalyst in allylic etherification of cinnamyl chlorides with up to 98:2 regioselectivity (19 examples). Both the solvent effect and the exsiccant reaction condition are crucial to the reactivity and selectivity. Preliminary mechanism studies and the demonstration of Fluoxetine synthesis were presented in this work as well. (C) 2013 Elsevier Ltd. All rights reserved.
