Novel oxyfunctionalized phosphonite ligands for the hydroformylation of isomeric n-olefins
Industrially relevant selectivities and turnover frequencies of up to 18710 h-1 are achieved with novel 2,2'-dihydroxybiphenyl phosphonite ligands such as 1 in the rhodium-catalyzed hydroformylation of internal octenes. R1 = H, alkyl; R2 = OMe, tBu.
