Unusual products from CO/ethene reactions catalysed by β-ketophosphine and related complexes of rhodium

Using rhodium complexes of tertiary phosphines with carbonyl groups β to the P atom, ethene and CO react in methanol to give products involving increased chain growth (octane-3,6-dione, methyl 4-oxohexanoate) compared with PEt3 complexes and unsaturated products (methyl propenoate, penten-3-one and 1-methoxypentan-3-one from addition of methanol to penten-3-one); mechanistic studies suggest that the ligand carbonyl group prevents coordination of the keto group in the growing chain.

Complexes of Nickel(II), Palladium(II), and Platinum(II) with the β-Ketophosphines PBut2(CH2COR) (R=Ph or But)

The β-ketophosphines PBut2(CH2COR) (R=Ph or But) have been prepared by treating the α-bromoketones BrCH2COR with PBut2H and subsequent treatment with base.With hydrated nickel(II) chloride, complexes of the type trans-, in which the nickel is chelated by the tertiary phosphine enolate ion, are formed rapidly.In contrast, with or these β-ketophosphines, even on prolonged boiling in alcohols, give complexes of type trans-t2(CH2COR)>2>.However, when these chlorocomplexes are treated with sodium 2-methoxyethoxide, ring closure occurs to give the bis(chelates) trans-.Proton and 31P n.m.r. and i.r. data are given.
