Application:	(R)-(-)-4,12-Bis(diphenylphosphino)-[2.2]-paracyclophane may be used as a ligand in the following processes: • Enantioselective reductive cyclization of 1,6-enynes via asymmetric hydrogenation in the presence of a rhodium catalyst to form alkylidene-substituted heterocycles. • Asymmetric hydroboration of 3,3-disubstituted cyclopropenes to form 2,2-disubstituted cyclopropyl boronates. • Asymmetric ring-opening reactions of azabenzonorbornadienes in the presence of zinc(II) triflate and palladium(II) acetate to form aminodihydronaphthalenes.
Application:	Efficient ligand for asymmetric hydrogentation of dehydroamino acids, methyl esters and keytones.
Legal Information:	Sold in collaboration with Johnson Matthey Catalyst for research purposes only. US5874629 and any patents arising therefrom apply.
Packaging:	100 mg in clear glass bottle
Packaging:	500 mg in amber glass bottle
