Catalyst composition and process for oligomerization of ethylene

The present invention relates to a catalyst composition for oligomerization of ethylene, comprising a chromium compound; a ligand of the general structure R 1 R 2 P-N(R 3 )-P(R 4 )-N(R 5 )-H, wherein R 1 , R 2 , R 3 , R 4 and R 5 are independently selected from halogen, amino, trimethylsilyl, C 1 -C...
