Nucleophilic Aromatic Substitution Reactions of Fluorobenzenechromium Comwith P-Chiral Secondary Phosphine—Boranes: Synthesis of Optically Pure
36- 175 plexes
P-Chiral (Dialkyl)arylphosphine—Boranes. — Reaction of fluorobenzene—tricarbonylchromium complexes like (I) with optically pure phosphine—borane complexes
like (II) provides access towards title enantiopure P-chiral (dialkyl)arylphosphine—boranes (III) and (VI). The P-chiral phosphine (VII) bearing a second fluorine atom can
be applied towards nucleophilic substitution reactions to give a diversity of optically
active arylphosphine—borane complexes. — (KATAGIRI, K.; DANJO, H.;
