An acelylenically of a diene compound and/or method of manufacturing

Provided is a novel method for producing a compound having acetylene bonds and/or a diene. The method for producing a compound having acetylene bonds and/or a diene is characterized in that at least one selected from the group consisting of ketone compound (I), ketone compound (II), aldehyde compound (III), aldehyde compound (IV), and aldehyde compound (V) is dehydrated in the presence of a catalyst wherein a carrier containing silica supports at least one selected from the group consisting of compounds containing group 1 metal elements, compounds containing group 2 metal elements, group 1 metal elements, and group 2 metal elements.

DIMERIZATION AND CODIMERIZATION OF MONOSUBSTITUTED ACETYLENES BY THE ACTION OF PALLADIUM COMPLEXES

The linear dimerization and codimerization of C5-C12 α-acetylenes with palladium catalyst were investigated systematically.It was shown that the catalyst system Pd(acac)2-PPh3-(C2H5)3Al can be used for selective transformation of α-acetylenes into the corresponding alkenylacetylenes with fairly high yields.

METAL COMPLEXES WITH ALLYLANILINES. IV. SYNTHESIS AND REACTIVITY OF RHODIUM(I) COMPLEXES WITH 2-ALLYLANILINE AND N-ALLYLANILINE

The reaction of 2-allylaniline (2aa) with 2 (I) in toluene or benzene at room temperature affords the dimer 2 (II) in which the ligand acts as bidentate, being coordinated to the metal through the N atom and the olefinic group.II in CH2Cl2, isomerizes 2aa to trans-2-propenylaniline.This reaction goes also catalytically.Heating of II in benzene affords 2-methyl-indoline.N-Allylaniline (naa) reacts with I to give the deep violet diamagnetic complex Rh2Cl2(naa)3 (III), which is converted slowly into 2.When III is heated with an excess of naa, the ligand is catalytically transformed into propene, azobenzene, N-n-propylaniline, N-i-propylaniline, N-allylideneaniline and aniline, as the more abundant products.Moreover, III reacts with diphenylacetylene to afford 2,5-dihydro-1,2,3-triphenyl-4-methyl-pyrrole.The reaction of III with methylacetylene follows a more complex path, and products of dimerization and trimerization of the alkyne have been isolated.Carbon dioxide influences the oligomerization reaction.
