Chelating diphosphines designed to coordinate in diequatorial or in apical−equatorial positions were synthesized, and their effects on the regioselectivity of rhodium catalyzed 1-hexene hydroformylation were observed. Only diequatorial coordination was observed for 2,2‘-bis[(diphenylphosphino)methyl]-1,1‘-biphenyl (BISBI) complexes (BISBI)Ir(CO)2H (8) and [BISBI-(3,5-CF3)]Ir(CO)2H (10), and only apical−equatorial coordination was seen for 1,2-bis(diphenylphosphino)ethane (DIPHOS) complexes (DIPHOS)Ir(CO)2H (14) and [DIPHOS-(3,5-CF3)]Ir(CO)2H (15). For the trans-1,2-bis[(diphenylphosphino)methyl]cyclopropane (T-BDCP) complexes, a mixture of diequatorial and apical−equatorial complexes was seen. For (T-BDCP)Ir(CO)2H (12), 12-ae was favored over 12-ee by 63:37, but for [T-BDCP-(3,5-CF3)]Ir(CO)2H (13) the conformational preference was reversed and a 10:90 ratio of 13-ae:13-ee was seen. The electron withdrawing groups in the equatorial positions of BISBI-(3,5-CF3) (1) and T-BDCP-(3,5-CF3) (2) led to an increase in n-aldehyde regioselectivity in rhodium catalyzed hydroformylation. However, electron withdrawing aryl substituents in the apical positions of DIPHOS-(3,5-CF3) (3) led to a decrease in n-aldehyde regioselectivity in rhodium catalyzed hydroformylation.}, author={Casey, Charles P. and Paulsen, Evelyn Lin and Beuttenmueller, Eckart W. and Proft, Bernd R. and Petrovich, Lori M. and Matter, Brock A. and Powell, Douglas R.}, year={1997} } @article{casey_petrovich_1995, title={(Chelating diphosphine)rhodium-Catalyzed Deuterioformylation of 1-Hexene: Control of Regiochemistry by the Kinetic Ratio of Alkylrhodium Species Formed by Hydride Addition to Complexed Alkene}, url={http://dx.doi.org/10.1021/ja00127a014}, DOI={10.1021/ja00127a014}, abstractNote={ADVERTISEMENT RETURN TO ISSUEPREVArticleNEXT(Chelating diphosphine)rhodium-Catalyzed Deuterioformylation of 1-Hexene: Control of Regiochemistry by the Kinetic Ratio of Alkylrhodium Species Formed by Hydride Addition to Complexed AlkeneCharles P.
