| abstract |
The invention relates to new Pd and Ni complexes with a biphenyl-2-ylphosphine of the formula (I) DOLLAR F1 in which DOLLAR AR · 1 · and R · 2 · are identical or different and straight-chain or branched alkyl having 1 to 8 C atoms, cycloalkyl with 4 to 8 ring C atoms, (C¶2¶-C¶12¶) alkenyl, (C¶2¶-C¶12¶) alkynyl, unsubstituted or substituted phenyl, where the Substituents 1 to 3 in number and can have the meaning (C¶1¶-C¶4¶) -alkyl, (C¶1¶-C¶4¶) -alkoxy, F or CF¶3¶, or heteroaryl mean; or R · 1 · and R · 2 · together are a 1, omega-alkanediyl chain with 3 to 8 C atoms; DOLLAR AR3 hydrogen, C¶1¶-C¶12¶-alkyl, (C¶2¶-C¶12¶) -alkenyl, (C¶2¶-C¶12¶) -alkynyl, phenyl, naphthyl , Heteroaryl, Li, Na, K, MgCl, MgBr, Mgl, Mg¶0.5¶, ZnCl, ZnBr, Zn¶0.5¶, POPhenyl¶2¶, PO- (C¶1¶-C¶8¶ -Alkyl) ¶2¶, PO¶3¶- (C¶1¶-C¶8¶Alkyl) ¶2¶, SO¶2¶R, SOR, SiR¶3¶, C (= O) R, C ( = O) NR¶2¶, C (= O) NHR or C (= O) OR; or R · 3 · is a polymeric matrix which is bonded directly or via an aliphatic, aromatic or araliphatic bridge member to the R · 3 · adjacent phenolic oxygen atom; DOLLAR A and R · 4 · to R · 11 · are hydrogen or substituents. DOLLAR A The novel complexes can be used as catalysts for C, C, C, N and C, O couplings, e.g. B. for Suzuki, Grignard or Stille clutches and for Heck reactions. |
