Rhodium (I) bis-olefin complexes Cp*Rh(VTMS)(2) and CpRh(VTMS)(2) (Cp* = C(5)Me(5), Cp = C(5)Me(4)CF(3), VTMS = vinyl trimethylsilane) were found to catalyze the addition of aromatic aldehydes to olefins to form ketones. Use of the more electron-defi

The bis(olefin) complex [C5Me5Co(C2H3SiMe3)2] (6) reacts with pyridine at 22 °C to give the pyridine olefin complex [C5Me5Co(C2H3SiMe3)(C5H5N)] (7). The addition of excess pyridine does not result in the formation of a bis(pyridine) adduct. Thermoly

Ein Gemisch isomerer Aldehyde wird bei einer von [C5Me5Rh(olefin)2]-Komplexen katalysierten Isomerisierung von Alkylaldehyden gebildet. Dies ist eine indirekte Methode zur Beeinflussung des n:iso-Verhaltnisses von Aldehyden, die bei Hydroformylierung

A mixture of isomeric aldehydes is formed in a catalytic isomerization of alkyl aldehydes with [C(5)Me(5)Rh(olefin)(2)] complexes. This process offers an indirect method for altering the n:iso ratio of aldehydes formed in hydroformylation reactions.

The rhodium bis-olefin complex [C5Me5Rh(C2H3SiMe3)2], 1, has been shown to be a catalyst for the selective addition of olefins to the ortho position of aromatic ketones. The addition of vinyltrimethylsilane to benzophenone was studied by NMR spectros

A series of [C5Me5Rh(CH2CHR)2] complexes (1a−e) have been prepared in which the olefin bears a bulky silyl substituent, R = (a) SiMe3, (b) SiMe2OEt, (c) Si(OiPr)3, (d) SiMe(OSiMe3)2, (e) SiPh2OiPr. The solid-state structure of 1c has been determine
