说明

General description

Copolymers of 1-eicosene and ethene has been prepared using the methylaluminoxane activated dimethylsilanediyl(tetracyclopentadienyl)(tert-butylamido)-titanium dichloride catalyst system. It polymerizes in the presence of zirconocene and hafnocene catalyst to yield poly-1-eicosene.

Application

1-Eicosene was used in the synthesis of (Z)-tetracos-5-enoic acid and racemic cis-4-(2-octadecylcyclopropane-1-yl)-butanoic acid.

(Z)-tetracos-5-enoic acid and racemic cis-4-(2-octadecylcyclopropane-1-yl)-butanoic acid have been prepared from 1-eicosene by a new facile route. Periodic acid cleavage of the epoxide of 1-eicosene gave nonadecanal which was condensed with 4-carboxybutyltriphenylphosphonium bromide to give predominately (Z)-tetracos-5-enoic acid.
