The Catalytic Conversion of Olefins, V l ) Synthesis of 4,5-Dimethyl-l-cis, 4-cis, 7-trans-cyclo-decatriene. Cooligomerization of Butadiene und 2-ButyneNickel ligand catalysts cooligomerize butadiene and 2-butyne to 4,5-dimethyl-1-cis, 4-cis, 7-trans-cyclodecatriene (1) in a yield of over 95% based on reacted 2-butyne. 1 rearranges thermally to give 1,2-dimethyl-4,5-divinylcyclohexene (2) faster than 1-cis, 5-trans-cyclodecadiene rearranges to 1,2-divinylcyclohexane.
Notes:
Ligand/Nickel-Katalysatoren vermitteln die Misch-Cyclooligomerisation von Butadien und Butin-(2) zum 4.5-Dimethyl-(cis.cis.trans)-cyclodecatrien-(1.4.7) (1) in Ausbeuten von über 95%, bezogen auf umgesetztes Butin-(2). 1 lagert sich thermisch schneller in 1.2-Dimethyl-4.5-divinyl-cyclohexen (2) um als cis.trans-Cyclodecadien-(1.5) in 1.2-Divinyl-cyclohexan.
