Addition von α-Aminosäureestern an den Cycloheptadienyl-Liganden von [(η5-C7H9)Fe(CO)3]+ und den Allyl-Liganden des chiralen [(η3-C3H5)Mo(Cp)(CO)(NO)]+ / Addition of α-Amino Acid Esters to the Cycloheptadienyl Ligand of [(η5-C7H9)Fe(CO)3]+ and of the Allyl Ligand of the chiral [(η3-C3H5)Mo(Cp)(CO)(NO)]+

Abstract

The reactions of GlyOEt, L-AlaOMe, L-ValOMe or L-PheOMe with cycloheptadienyltricarbonyliron tetrafluoroborate afford the neutral 5-exo-amino substituted cycloheptadiene complexes [(η4-C7H9NHCHRCO2R’)Fe(CO)3] which are formed as two diastereoisomers with R = Me, CHMe2, CH2Ph. The addition of GlyOEt, L-AlaOMe or L-VaOMe to the chiral [(η3-C3H5)Mo(Cp)(CO)(NO)]BF4 gives the olefin complexes [(η2-CH2=CH-CH2- NH2CHRCO2R’)Mo(Cp)(CO)(NO)]BF4.
