PHOSPHORORGANISCHE VERBINDUNGEN 105. Synthese chiraler und achiraler ditertiaerer 1-Phosphino-2-Aminoethan-Derivate (=P-CH2-CHR-N=) und einige Anwendungen

Primary amines with an optical active ligand add to vinyl- and propenylphosphonium salts according the reaction schemes (5) and (6), forming compounds of the type E and F.F contains a new asymmetric center in the bridge giving rise to the formation of a mixture of diastereomers, which can be resolved.Phosphonium salts of the type E and F with a benzyl group on the phosphonium center are cleaved reductively by alkali amalgams (Li/Hg; Na/Hg; K/Hg) forming tertiary phosphines with an aminogroup in the β-position.The reductive cleavage with alkali amalgams is superior to the cathodic cleavage.Application: The synthesis of Ni(0)- and Pd(0)-complexes of type J fails.Bis-phosphine complexes of type 21 are formed.The rate of the homogeneous hydrogenation of 1-hexene with Rh(I)-complexes (containing G as a ligand) has an optimum with respect to a Rh/Co-catalyst proportion of 1:2 to 1:1.6.The optical induction of the homogeneous hydrogenation of Z-N-Acylamino-cinnamic acid is lower than 5percent.
