Abstract

Results.±First of all, we compared the activity and selectivity of the (á)-(R)-binap ligand (R)-5 with its commercially available polymer-supported analogue (R)-66), using triflate as the counter ion of Rhá ([RhI (ligand)(cod)] CF3SO3; cod àcycloocta-1, 5-diene), an anion not mentioned in the Japanese patent [3e, f]. Under these conditions, the ligand (R)-6 exhibited very similar reactivity and selectivity, even at 0.25 mol-% of the catalyst (ie of the ligand) ...
