摘要：
The present invention is related to a method for oligomerizing olefinic monomers under oligomerization conditions to form higher olefins. The novel method comprises contacting a feed comprising the olefinic monomers with a catalyst composition comprising the reaction product of: (a) a compound having a formula selected from the group consisting of M[S2C2(RaRb)]2 and M[S2C6(R1R2R3R4)]2, wherein M is a late transition metal, Ra, Rb, R1, R2, R3 and R4 are independently selected and may be the same or different and are selected from hydrogen, electron-withdrawing groups and unsubstituted and substituted hydrocarbyl groups; and (b) an activating cocatalyst. The improved method advantageously relates to oligomerizing olefinic monomers from feed streams having contaminants, especially sulfur-containing contaminants.
