preparation of (1r,2r)-(+)-1,2-diaminocyclohexane-n,n’-bis(2-phenylphosphine-1-naphthoyl)_kain industrial additive
background and overview[1] (1r,2r)-(+)-1,2-diaminocyclohexane-n,n’-bis(2-phenylphosphine-1-naphthoyl) is an organic phosphine ligand commonly used in transition metal catalyzed reactions. this chiral coordination has proven to be very successful in the amination of butadiene monoepoxides, a type of epoxide and a potential prospect for asymmetric synthesis starting materials (or substrates). preparation[1] add 1.90g (5.33mmol) 2-diphenylphosphine-1-naphthoic acid and 42ml dichloromethane…
