Rhodium catalysed hydroformylation using slim phosphate ligands to improve selectivity

Article abstract of DOI:10.1016/0022-328X(93)83038-W

Catalysts based on 1COCHCOR¹)(CO)2> and a phosphite are active for hydroformylation of hex-1-ene under very mild conditions; very bulky phosphites such as (2-^tBu-4-MeC6H3O)3P, 3, give much olefin isomerization, while the slim caged phosphite ligands, P(OCH2)3CR², show high regioselectivity towards formation of n-C6H13CHO.
