N2 - The syntheses and reactivity of the first rhodaboratranes, [RhX(PPh 3){B(mt)3}] (X = Cl, H) and [Rh-(η4-C 8H12){B(mt)3}]Cl, are described in detail together with preliminary investigations of the mechanistic processes involved. The subsequent exploitation and circumvention of the lability of [RhCl(PPh 3){B(mt)3}] in the synthesis of a range of isonitrile, [Rh(CNR)(PPh3){B(mt)3}]Cl (R = tBu, C 6H3Me2-2,6, C6H2Me 3-2,4,6), phosphine, [Rh(PMe3)n(PPh 3)2-n{B(mt)3}]Cl (n = 0, 1, 2), and dialkyldithiocarbamate, [Rh(S2-NEt2){B(mt) 3}]Cl, complexes is described, along with the attempted synthesis of [Rh(CNtBu)2{B(mt)3}]Cl from [Rh(η4-C8H12){B(mt)3}]Cl. Single-crystal X-ray structure determinations of [Rh(L)(L′){B(mt) 3}]-Cl (L = CNtBu, CN(C6H3Me 2-2,6), L′ = PPh3; L = L′ = PMe3) are reported.
