ETHYLENE TETRAMERIZATION CATALYST SYSTEMS AND METHOD FOR PREPARING 1-OCTENE USING THE SAME

Disclosed herein is a method of preparing 1-octene at high activity and high selectivity while stably maintaining reaction activity by tetramerizing ethylene using a chromium-based catalyst system comprising a transition metal or a transition metal precursor, a cocatalyst, and a P—C—C—P backbone structure ligand represented by (R1)(R2)P—(R5)CHCH(R6)—P(R3)(R4).

Contributions to the Chemistry and Structures of Tris(diphenylphosphino)ethene and 1,1,4,4-Tetrakis(diphenylphosphino)-1,3-butadiene

Reaction of tris(diphenylphosphino)ethene (1), obtained by base-catalyzed hydrophosphorylation of Ph2PCCPPh2 with Ph2PH, with 2 equivalents of H3B*OC4H8 affords 1,1-bis(boranatodiphenylphoshonio)-2-(diphenylphosphino)ethene (2).Methylation of 1 with MeI gives the monoquaternary salt 3, the molecular structure of which was determined by X-ray crystallography.A trisulfide 4 is available by treatment of 1 with elemental sulfur. - 1,1,4,4-Tetrakis(diphenylphosphino)-1,3-butadiene (5) was isolated as a byproduct in the synthesis of 1. 1,1,4,4-substitution was established by X-ray analysis of the tetrasulfide 6, obtained by treatment of 5 with elememtal sulfur.Reaction of 5 with 2 equivalents of Mo(CO)6 yields the symmetrical, dinuclear complex 7. - Key Words: Tris(diphenylphosphino)ethene derivatives / 1,1,4,4-Tetrakis(diphenylphosphino)-1,3-butadiene derivatives / Molybdenum complex
