title: Alkyl group versus hydrogen atom transfer from metal alkyls to macrocyclic rhodium complexes.
abstract: Macrocyclic rhodium(II) complexes LRh(H2O)(2+) react with (dmgH)2(H2O)CoR and with (H2O)5CrR(2+) by alkyl transfer for R = CH3 to generate L(H2O)RhCH3(2+). When R = C2H5, C3H7 or C4H9, the reaction takes place by hydrogen atom abstraction from the coordinated alkyl and produces L(H2O)RhH(2+) and an α-olefin.
