    Substrate Selective Catalysis by Rhodium Metallohosts
    摘要:
    A novel supramolecular catalyst functioning according to the principles of enzymatic catalysis is described. It consists of a basket-shaped molecule to which a catalytically active Rh(I) complex is attached. The catalyst selectively hydrogenates and isomerizes allyl-substituted dihydroxyarene substrates that are bound in its cavity. The reactivity of this supramolecular catalyst and its affinity for several substrates is compared with that of the corresponding catalyst without a binding site. Features known from enzymatic catalysis, e.g. Michaelis-Menten kinetics and rate enhancement by cooperative binding, are described and discussed.

    used alone as the catalyst precursor produces 54 and 72.9% of aldehydes when used with a six-fold excess of P(OPh)3. Complex (1) modified with P(OPh)3 catalyses hexen-1-e hydroformylation with a 73.6–84.6% yield of aldehydes. Under hydroformylation reaction conditions, the PO ligand is removed from the coordination sphere of (1) and complexes of the form HRh(CO)P(OPh)3}3 and HRhP(OPh)3}4 are formed

During the catalytic process, rhodium(I) carbene complexes, [Rh(NHC)(P(OPh)3)2X], reacted with H2/CO, giving a catalytically active rhodium(I) hydrido complex containing an N-heterocyclic carbene ligand. The presence of [HRh(CO)(P(OPh)3)3] and [Rh(NHC)(P(OPh)3)(CO)X] complexes in the catalytic system has been confirmed. When P(OCH2CF3)3 was used as modifying ligand with

  • 1,5-Hexadiene selective hydroformylation reaction catalyzed with Rh(acac){P(OPh)3}2/P(OPh)3 and Rh(acac)(CO)(PPh3) / PPh3 complexes
    作者:A.M. Trzeciak、J.J. Ziółkowski
    DOI:10.1016/0022-328x(94)87017-9
    日期:1994.1
    Hydroformylation of 1,5-hexadiene, catalyzed by the system Rh(acac)P(OPh)(3)}(2)/P(OPh)(3) (I), leads to the formation of mono- and dialdehydes, 4-heptenal, 2-Me-3-hexenal and octane-1,8-dial, 2,5-Me(2)-hexanedial respectively. The yield of dialdehydes increases with temperature and pressure and reaches 100% at 80 degrees C and 10 atm of CO/H-2=1. The reaction catalyzed by Rh(acac)(Co)(PPh(3))/PPh(3) (II) system produces, besides dialdehydes, monoaldehydes with a terminal double bond, namely 6-heptenal and 2-Me-5-hexenal. The migration of the double bonds in monoaldehydes depends mainly on the donor properties of modifying ligands. Phosphine when used as a modifying ligand (II), because of its strong donor properties, restricts isomerization (double bond migration) and diminishes yield of 4-heptenal. In contrast, when less strongly donating ligands such as phosphites are used as modifying ligands (I), independently of its steric properties, 4-heptenal is the main reaction product.
