Generation of functionalized aryl and heteroaryl aluminum reagents by halogen-lithium exchange.
In: Chemical Communications, Vol. 49, Nr. 62: S. 6953-6955
Various functionalized aryl and heteroaryl aluminum reagents were obtained by performing I-Li or Br-Li exchange reactions with the corresponding unsaturated organic halides in the presence of i-Bu2AlCl. By means of an appropriate catalyst, the resulting new aluminum species were directly acylated, allylated or arylated. 1,4-Michael additions to enones have also been achieved.
