Abstract:
A neutral or cationic transition metal catalyst for use in a hydroformylation of epoxide derivatives comprising a compound represented as formula (A-2) or a compound synthesized from the reaction of (A-2) with a compound having one or more active radicals: wherein: M represents Ir having an oxidation state of 1 or 3; (a) is a 1-valence anion of BF4 â€”, PF6â€”, CIO4â€”, SO3CF3â€” or BRâ€²4â€” or a 2-valence anion of CO32âˆ’ or SO42âˆ’Râ€² represents hydrogen; an alkyl radical of saturated or unsaturated aliphatic chain type or ring type hydrocarbons or aromatic hydrocarbons having C1ËœC10; or a halogen atom of F, Cl, Br or I; m is an integer of 0, 2 or 4 when (a) is a 1-valence anion or a halogen atom, and m is 0, 1 or 2 when (a) is a 2-valence anion; R1ËœR5 are each independently selected from hydrogen; saturated or unsaturated aliphatic or aromatic hydrocarbons of C1ËœC20; saturated or unsaturated aliphatic or aromatic hydrocarbons having nitrile radicals at the end or at the middle; saturated or unsaturated aliphatic or aromatic hydrocarbons having amine radicals at the end or at the middle; and halogen atoms of F, Cl, Br or I; aâ€² and bâ€² in Xaâ€² and Ybâ€² are integers of 0Ëœ2, with aâ€²+bâ€²=2; Xaâ€² is a halogen atom of F, Cl, Br or I; a hydroxy radical; an alkoxy including a saturated or unsaturated aliphatic or aromatic hydrocarbon of C1ËœC10; a nitrile including saturated or unsaturated aliphatic or aromatic hydrocarbons of C1ËœC10; or a compound expressed by the formulas (I), (II) or (III): â€ƒQ1 is N, P, As or Sb; Q2 and Q3 are each independently selected from P, As or Sb; Rc, Rd and Re are each independently selected from hydrogen; alkyl radicals including saturated or unsaturated aliphatic or aromatic chain type or ring type hydrocarbons of C1ËœC20, or aromatic hydrocarbons; aliphatic hydrocarbons having carbon chains of of C1ËœC5; cyclohexyl; phenyl; benzyl; compounds including at least one or more nitrile radicals, amine radicals having a formula RfRgNâ€”, aldehyde radicals or ketone radicals in an aliphatic hydrocarbon or in a phenyl or in a benzyl; halogen atoms of F, Cl, Br or I; phosphine radicals; arsine radicals; or stibine radicals including saturated or unsaturated aliphatic or aromatic chain type or ring type hydrocarbons or aromatic hydrocarbons of C1ËœC30; c, d, and e in the Rc, Rd and Re, are integers of 0Ëœ3, with c+d+e=3; Rf and Rg are each independently selected from hydrogen; and alkyl radicals including saturated or unsaturated aliphatic or aromatic chain type or ring type hydrocarbons of C1ËœC20, aliphatic hydrocarbons, carbon chains of C1ËœC10 having no branches, carbon chains having branches, or ring type compounds; f and g are integers of 0Ëœ2, with f+g=2; and Ybâ€² is carbon monoxide; a halogen atom of F, Cl, Br or I; a hydroxy radical; or an alkoxy radical including saturated or unsaturated aliphatic or aromatic hydrocarbons of C1ËœC10.
