Abstract
A process for preparing primary substituted n-alkane compounds, comprising contacting the olefin product of an olefin metathesis reaction having an alpha-olefin as the reactant with a bis-cyclopentadienyl zirconium hydrohalide and, after contacting the product of the olefin-zirconium hydrohalide reaction with an electrophilic reagent, recovering said primary substituted n-alkane compound.
Claims1
A process for preparing primary substituted n-alkane compounds, comprising:
- (a) contacting an .alpha.-olefin having a carbon chain length greater than about C.sub.11 with an olefin metathesis catalyst which is a mixture comprising a tungsten hexahalide compound, a tetraalkyl tin compound, and ethyl acetate;
- (b) contacting the product of Step (a) with a biscyclopentadienyl zirconium hydrohalide generated in the reaction mixture;
- and
- (c) contacting the product of Step (b) with an electrophilic reagent selected from N-bromosuccinimide, bromine, iodine, and oxygen.
