L-Propyl-3-methylimidazolium

The results of unsymmetrical 7r-acid bidentate ligands, e.g., (81), have in the hydroformylation of ra-octenes was described. The preparation of seven such ligands was described. Thus, [Rh-(acac)(cod)]-catalyzed hydroformylation of ra-octene in the presence of a phosphinite ligand gave 94% ra-nonanal.295 A new upper-rim phosphacalix[4]arene 5,17-bis(diphenylphosphinomethyl)-25,26,27,28-tetrapropoxycalix[4]arene has been prepared. It reacted with [(cod)RhCl]2 to give a dirhodium complex that is an active catalyst for the hydroformylation of 1-octene and styrene.296 Rhodium complexes of [l-propyl-3-methylimidazolium+]2 [PhP(C6H4SO%)2] dissolved in the... 

The melting points and enthalpies of the three isomeric l-butyl-3-methylimida-zolium hexafluorophosphate salts [BMIM][PF6] [47] increase with the degree of chain branching, reflecting the changes in efficiency of the crystal packing as free-rotation volume decreases and atom density is increased. The same effects are also observed for the two isomers of l-propyl-3-methylimidazolium hexafluorophosphate [PMIM][PF6] [24],... 

In the case of the hydroformylation reaction, 46.5 mg (0.180 mmol) [Rh(acac)(CO)2 and 1.31 g [Prmim][TPPMS] (Prmim = l-propyl-3-methylimidazolium TPPMS = triphenylphosphine monosulfonate) were dissolved in 12 mL IL in a 30 mL CSTR. 

PMIM]2[PhP(CgH4S03)2] (PMIM = l-propyl-3-methylimidazolium) and [Rh2(OAc)4] dissolved in [bmim]PF5 was used as the catalyst for the homogeneous hydroformylation. For the SCGO2/IL biphasic system, both the ligand and the...
