A straightforward synthesis of unsymmetrical secondary phosphine boranes

A one-pot procedure for the synthesis of unsymmetrical alkyl-substituted secondary phosphine oxides is described. The sequential addition of N-benzylaniline to a solution of dichlorophenylphosphine and 1-methylimidazole in methylcyclohexane, separating of the protic ionic liquid formed, addition of Grignard reagent followed by hydrolysis gave unsymmetrical secondary phosphine oxides (SPOs) in high yield. The use of ionic liquids in the first step is essential and streamlined the synthesis. Unsymmetrical SPOs could be quantitatively reduced to secondary phosphine using a catalytic amount of Ti(OiPr)4 and tetramethyldisiloxane (TMDS) under mild reaction conditions.

CATALYTIC OLIGOMERIZATION OF OLEFINIC MONOMERS

A catalyst precursor composition comprising: a) a source of chromium, molybdenum or tungsten; b) a first ligand having the general formula (I); [in-line-formulae](R1)(R2)P—X—P(R3)(R4)??(I) [/in-line-formulae] wherein: X is a bridging group of the formula —N(R5)—, wherein R5 is selected from hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, a substituted heterohydrocarbyl group, a silyl group or derivative thereof; at least three of R1 to R4 are independently selected from optionally substituted aromatic groups, each bearing a polar substituent on at least one of the ortho-positions; and optionally one of R1 to R4 is independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; c) a second ligand having the general formula (II); [in-line-formulae](R1′)(R2′)P—X′—P(R3′)(R4′)??(II) [/in-line-formulae] wherein: X′ is a bridging group as defined for X of the first ligand, component (b), of general formula (I); at least R1′ and R2′ of R1′ to R4′ are independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; and optionally none, one or both of R3′ and R4′ are independently selected from an optionally substituted aromatic group bearing a polar substituent on at least one of the ortho-positions. The present invention also relates to a catalyst system comprising the catalyst precursor composition of the present invention and additional component; d) a cocatalyst. The present invention further relates to a process for the trimerization and tetramerization of olefinic monomers, particularly the trimerization and tetramerization of ethylene to 1-hexene and 1-octene, wherein the process comprises contacting at least one olefinic monomer with the catalyst system of the present invention.
