High-melting phosphonium tosylates are synthesised and applied for the first time as solvents in catalytic hydroformylation reactions; variation in the substituents attached to phosphorus can lead to markedly different results; the catalyst systems are non-corrosive, easily manipulated and can readily be recovered and reused.

Ionicliquids are currently attracting considerable interest from chemists, partly due to their potential as “green” alternatives to volatile molecular organic solvents. Phosphonium ionicliquids have received much less attention than ammonium salts in the past, but the situation is changing. The salts are applied in the liquid state but in this work, salts with higher melting points than is generally
