Rh-dppf

The Rh-catalyzed hydroacylation of alkynes is also possible. Reaction of salicyl-aldehyde (611) with 4-octyne using an Rh-DPPF complex gave the unsaturated ketone 612 in high yield [236],... [Pg.295]

The temperature-dependent P NMR spectrum of [Rh(dppf-P,P )2][BPh4] reveals a different kind of solution fluxionality [65], which invokes changes in both... [Pg.43]

More recentiy, a rhodium-catalyzed carbonylation of arylzinc compounds was developed by Takagi [117]. In the presence of an Rh-dppf catalyst under 1 bar of CO using 1,2-dibromoethane as the oxidant, carbonylative homo-coupling of arylzinc compounds was achieved, affording symmetrical diaryl ketones in good yields (Scheme 8.33). Under similar conditions, Pd or Ni catalysts induced oxidative homo-coupling of zinc reagents to yield diaryls instead. [Pg.162]

Cobalt and Rhodium The molecular structure of [(Pr 2PCH2)2)Rh((tl cat)-Beat ], HBcat - catecholatoborane, prepared by reaction of [RhQ(N2)(n 3)2] with catecholatoborane, has been reported. The crystal structure of [Rh(dppf)(ii -C5H5)BI%3], ri pf s diphenylphosphinofenocene, has also been described. ... [Pg.342]
