Journal ArticleDOI
Diphosphines with natural bite angles near 120.degree. increase selectivity for n-aldehyde formation in rhodium-catalyzed hydroformylation
Charles P. Casey,Gregory T. Whiteker,Margaret G. Melville,Lori M. Petrovich,James A. Gavney,Douglas R. Powell +5 more
TL;DR: In this paper, the use of 2,2{prime}-bis[(diphenylphosphino)methyl]1,1{prime})-BISBI ligands as ligands in rhodium-catalyzed hydroformylation has been studied.
Journal ArticleDOI
The Natural Bite Angle of Chelating Diphosphines
TL;DR: In this paper, the natural bite angles of chelating diphosphine ligands have been determined by molecular mechanics calculations using the MACROMODEL program with a modified AMBER force field.
Journal ArticleDOI

TL;DR: In this article, the 1H and 13C NMR chemical shifts of 48 industrially preferred solvents in six commonly used deuterated NMR (CDCl3, acetone, DMSO-d6, acetonitrile-d3, methanol-d4, and D2O) are reported.

TL;DR: Bisphosphite 11 with a 2,2'-biphenol bridge was found to be the best overall ligand for asymmetric hydroformylation of allyl cyanide with up to 80% ee and regioselectivities (branch-to-linear ratio, b/l) of 20 with turnover frequency of 625 [h(-)(1)] at 35 degrees C.
