Energy-Minimized Structures and Calculated and Experimental Isomer Distributions in the Hexaamine-Cobalt(III) System 3+ with the Chiral Facially-Coordinating Triamine (L=Butane-1,2,4-Triamine)
Butane-1,2,4-triamine (trab) is the smallest tridentate aliphatic unsubstituted chiral triamine.With optically pure trab, there are three, with racemic trab five isomers of 3+.One of the five isomers is centrosymmetrical, the others are chiral.
Synthesis of New Optically Active Bis- and Tris(phosphines)
The synthesis of new optically active alkanediylbis- and alkanetriyltris(diphenylphosphines) is described.Easily accessible optically pure lactones and carboxylic acids are reduced to the alcohols, tosylated and reacted with lithium diphenylphosphide to give the corresponding phosphines.
