A convenient synthetic protocol to 1,2-bis(dialkylphosphino)-ethanes

1,2-Bis(dialkylphosphino)ethanes are readily prepared from the parent phosphine oxides, via a novel sodium aluminium hydride/sodium hydride reduction protocol of intermediate chlorophosphonium chlorides. This approach is amenable to multi-gram syntheses, utilises readily available and inexpensive reagents, and benefits from a facile non-aqueous work-up in the final reductive step.

Process for the preparation of substituted aromatic compounds

A process for the preparation of a substituted aromatic compound in which a chloroaromatic compound and an alkyl-, alkenyl- or aryl-boronic acid ester or anhydride are coupled in the presence of palladium and a lipophilic aliphatic phosphine comprising at least one branched aliphatic group or a lipophilic aliphatic Dis(phosphine). Preferred phosphines include triisopropyl, triisobutyl and tricyclohexylphosphine.

Co-dimerization of vinyl aromatics with α-monoolefins

The invention concerns a process for the co-dimerization of a vinyl aromatic monomer (e.g. styrene) with an α-monoolefin monomer (e.g. ethylene, propylene or 1-butylene), using a catalyst composition comprising palladium, an anion of a strong acid and an aliphatic diphosphine.
