  studied as catalyst precursors in the isomerising methoxycarbonylation of methyl oleate, and were found to convert methyl oleate into the corresponding linear α,ω‐diester (L) with 70–80 % selectivity. The products of this catalytic reaction with the known [1,2‐(tBu2PCH2)2C6H4}Pd(OTf)2] complex (5 h) were fully analysed, and revealed the formation of the linear α,ω‐diester (L, 89.0 %), the methyl‐branched

  A solid catalyst for olefin polymerization and a process for producing an olefin polymer are provided. The polymer has a small content of a component which is dissolved out into a low temperature organic solvent, such as a low-molecular weight component and an amorphous component. The solid catalyst is obtained by bringing a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an aliphatic carboxylate; an organoaluminum compound; and a compound represented by formula (I) into contact with each other: wherein R 1 is a hydrocarbyl group having 1 to 10 carbon atoms, R 2 is a hydrogen atom, a halogen atom or a hydrocarbyl group having 1 to 16 carbon atoms, and the R 1 the R 2 groups are independently the same or different, and the respective R 1 groups and R 2 groups may be joined with each other to form a ring.
