Scholarcy highlights

  • The progress made in the field of homogeneous catalysis during the last five to six years has led, inter alia, to the development of highly selective catalysts for asymmetric syntheses
  • Homogeneous asymmetric hydrogenation, using well defined transition metal catalysts, may be achieved with optical yields of 85 to 90% or more
  • In which the chiral centers are generated by CC bond formation, can result in optical yields of 70 to 80%
  • Catalysts which induce optical activity through the formation of CC bonds have been developed from π-allylnickel halides, Lewis acids, and phosphanes containing chiral C atoms
  • The results obtained signify a breakthrough in an area of catalysis previously restricted to syntheses involving enzymes
