Abstract

Abstract : XBphos-Rh constitutes the first example of halogen bonding as the driving force behind the assembly of a transition-metal catalyst for hydroborations. Abstract : The use of halogen bonding as a tool to construct a catalyst backbone is reported. Specifically, pyridyl- and iodotetrafluoroaryl-substituted phosphines were assembled in the presence of a rhodium(i ) precursor to form the corresponding halogen-bonded complexXBphos-Rh . The presence of fluorine substituents at the iodo-containing supramolecular motif was not necessary for halogen bonding to occur due to the template effect exerted by the rhodium center during formation of the halogen-bonded complex. The halogen-bonded supramolecular complexes were successfully tested in the catalytic hydroboration of terminal alkynes.
