Atom-efficient Pd-catalyzed cross-couplings of chloroarenes with triarylbismuth reagents

Various Pd-catalyzed protocols have been developed for the atom-efficient cross-coupling of chloroarenes with triarylbismuth reagents. Using the developed protocols, an efficient synthesis of unsymmetrical biaryls in good to excellent yields was achieved by employing electron-deficient chloroarenes and a range of triarylbismuth reagents.

Fe[(C5H4)NHPh]2 (2a) was prepared from 1,1?-dibromoferrocene and N-phenylacetamide by an Ullmann reaction and subsequent basic solvolysis of the coupling product Fe[(C5H 4)N(COMe)Ph]2 (1a). This solvolysis failed in the case of the bulkier Fe[(C5H4)N(COMe)(2,6-Me2C 6H3)]2 (1b). Fe[(C5H 4)N(2,6-Me2C6H3)]2 (2b) and Fe[(C5H4)N(2,4,6-iPr3C6H 2)]2 (2c) were obtained by Hartwig-Buchwald type cross-coupling of 1,1?-diaminoferrocene with the respective aryl bromide.

Palladium Nanoparticles?Polypyrrole Composite as Effective Catalyst for Fluoroalkylation of Alkenes

Abstract: Palladium nanoparticles?polypyrrole composite (Pd/PPy) catalyzes the addition of perfluoroalkyl halides to olefins to produce a variety of products with good yields. An effective fluoroalkylation technique tested with various olefins, fluoroalkyl halides and Pd/PPy was developed. The reaction proceeds highly efficient under mild phosphine-free reaction conditions with different substrates, easy catalyst recycling and provides a general and straightforward access to fluoroalkylated products. Furthermore, we were able to control whether the addition of perfluoroalkyl occurs with various monomer (fluoroalkylated alkene or alkane with RF and OH moieties) or dimer formation (under electrochemical conditions).
