    • Josiphos (1-(2-(diphenylphosphanyl)ferrocenyl)ethyldicyclo- hexylphosphane), Me-DuPHOS (DuPHOS=1,2-bis(2,5-dimethylphospholano)benzene, and BINAP (2,2′-bis(diphenylphosphanyl)-1,1′-binaphthyl), all gave ee values that were significantly below those obtained with DTBM-SEGPHOS. DTBM-MeO-BIPHEP (BIPHEP = 6,6′-dimethoybiphenyi-2,2′- diyl(diphenylphosphane)) afforded a comparable ee value, however, the extent of conversion was low in reactions run at -25°C.

    • The increased concentration was achieved by decreasing the amount of toluene used. 1,1,3,3-tetramethyl disilazane (TMDS; 6 equiv) gave best results.
