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.

Phosphonochloridous and phosphonous esters were prepared from the reaction of phenylphosphonous dichloride with 2,4-di-tert-butylphenol, 2,6-di-tert-butyl-4-methylphenol, and 2,4,6-tri-tert-butylphenol.Various synthetic methodologies, including phase-transfer catalysis, are described and compared.Phosphonous diesters containing two different substituted-phenyl moieties were prepared from phosphonochloridous monoesters.The reaction of O-(2,6-di-tert-butyl-4-methylphenyl)-phenylphosphonochloridite with N-methyldiethanolamine, n-octyl mercaptan, and water was studied and found to give a biphosphonite, phosphonothioite and phosphinate, respectively.
