This invention relates to a composition comprising a compound having a formula of M2(CO)m(PF3)n, wherein M is a group 9 metal (such as cobalt), m is 1, 2, 3, 4, 5, 6, or 7, n is 1, 2, 3, 4, 5, 6, or 7, and the sum of m and n is 8, that may be used as a hydroformylation pre¬catalyst for converting (such as hydroformylating) olefinic feeds, especially complex feeds comprising internal olefins and high degrees of branching.

Hydroformylation catalysts comprising fluorophosphine ligands and precursors thereof

Vinylidene olefins may undergo hydroformylation in the presence of an unmodified cobalt catalyst to form compositions comprising a mixture of alcohol molecules having a specified amount of branching. In particular, the compositions may feature a mixture comprising reduced hydroformylated reaction products of a vinylidene olefin comprising alcohol molecules represented by at least one of Structures 3-5. The mixture has an average of about 1.2 to about 2.1 branches per alcohol molecule. Rand Rmay be the same or different and comprise a branched or unbranched alkyl group having about 6 to about 14 carbon atoms, excluding branches. Variable m is an integer ranging from 0 to a number of carbon atoms in R. Ris a branched or unbranched alkyl group having m+1 carbon atoms less than R.

Branched alcohols formed from vinylidene olefins by hydroformylation and methods for production thereof

This invention relates to mono cyclopentadienyl pyridyl hydroxyl amine catalyst compounds represented by Formula I(a) or I(b): wherein: M is a group 3-12 metal; Ris a hydrocarbyl group or a silyl group; R, R, R, R, R, R, R, R, and Rare independently selected from the group consisting of hydrogen, hydrocarbyl, alkoxy, silyl, amino, aryloxy, halogen and phosphino, wherein any two adjacent R groups may be joined to form a saturated or unsaturated single or multicyclic hydrocarbyl ring or heterocyclic ring; and each Xand Xis independently an anionic leaving group or Xand Xmay be joined together to form a dianionic group.
