Aldehydes substituted in alpha position by alkyl residues as odoriferous and aroma substances

The present invention primarily relates to the use of an aldehyde, substituted in alpha position by an alkyl residue, of the formula having (I) a total of 13 C atoms, wherein R means an unbranched alkyl residue having 6, 7, 8 or 9 C atomsandR′ means an unbranched alkyl residue having 2, 3, 4 or 5 C atoms, or (II) a total of 15 C atoms, wherein R means an unbranched alkyl residue having 8, 9, 10 or 11 C atomsandR′ means an unbranched alkyl residue having 2, 3, 4 or 5 C atoms,or a blend comprising or consisting of two, three or more such aldehydes of type (I) and/or (II),as an odoriferous or aroma substance.

The Reduction of 3-Substituted Furans with Lithium and Ammonia

The reductions of 3-(1',1'-ethylenedioxynonyl)furan, 3-(1',1'-dimethoxynonyl)furan, 3-(1'-methoxynonyl)furan and 1-(furan-3'-yl))nonyl acetate with lithium and ammonia are described.The products result from benzylic type cleavage in the absence of an added proton source.When ethanol is present during the reduction extensive saturation and fission of the furan ring occurs.

COMPARATIVE STUDY OF TRIPHENYLAMINE, TRIPHENYLPHOSPHINE, TRIPHENYLARSINE, TRIPHENYLANTIMONY AND TRIPHENYLBISMUTH AS LIGANDS IN THE RHODIUM-CATALYZED HYDROFORMYLATION OF 1-DODECENE

Triphenylamine, triphenylphosphine, triphenylarsine, triphenylantimony and triphenylbismuth were evaluated on the basis of olefin to aldehyde converion, and also on the basis of the normal/iso (n/i) product ratio, as ligands in the rhodium-catalyzed hydroformylation of 1-dodecene.Two series of reactions were conducted which differed only in total reaction time (120 minutes vs 135 minutes) and in the ligand/rhodium ratio (60:1 vs 300:1).Both reactions series employed 35 grams of 1-dodecene, a 176 ppm rhodium charge, 100 psig of 1:1 H2/CO, and a reaction temperature of 90 deg C.In the 60:1 vs 330:1 reaction series, triphenylamine gave olefin conversion and n/i ratios of 2.0 percent, 2.0 vs 5.8 percent, 1.8; triphenylphosphine gave 95 percent, 4.4 vs 86.9 percent, 8.7; triphenylarsine gave 58 percent, 3.1 vs 85.8 percent, 3.5; triphenylantimony gave13.0 percent, 6.1 vs 3.5 percent, 9.1 respectively.Triphenylbismuth failed to promote hydroformylation in both reaction series.These data demonstrate that regiospecificity, as measured by the n/i product ratio, varies inversly to increased ligand basicity.
