It is a bisphosphit ligand used in the hydroformylation, hydrocyanation, hydroaminomethylation starting from short or long-chain olefins. Concerning the hydroformylation and according to industrial processes, the conversions are, depending on the substrate, up to 99% and yields up to 86% of the aldehydes. The ratio of linear to branched products is up to 99:1. It is an excellent industrial-process ligand because can be prepared chloride-free and it can be recycled.
