34. The examined nickel salts were purchased and used as received. The anhydrous nickel salts prepared from commercial nickel chloride and nickel acetate had a hygroscopic tendency
35. The examined bisphosphines are follows: (+)-DIOP, (S,S)-Chiraphos, (R,R)-Me-Duphos, (R,R)-Et-BPE, (R,R)-Quinox P*, (S)-PHOX, (R,S)-PPFA, (R,R)-Walphos, (R,S)-Taniaphos, (S)-BINAP, and 1,2-bis(dicyclohexylphosphino) ethane.
