COMNIUNtCATIONS

sities were registered to 25 = 5 0 ' . Of 8639 reflections, 5330 were independent (R,,, = 0.0406). An absorption correction based on $ scans was applied. The structure was solved with the heavy atom method and refined against F2 (SHELXL-93). Methyl H atoms were included by using rigid groups, all other H atoms with a riding model. Final w3R2 = 0.0732 based on F2 for all data, conventional R(F) 0.0309, for 360 parameters and 162 restraints; max.

This work describes a Pd-catalyzed coupling of ferrocene al-derivative 10) and of course amides. A minor by-product of the coupling reaction, namely the homo-dimer bis(ferrocene kyne derivatives to iodo amino acids. Ferrocene carboxylic acid propargyl amides were easily obtained in high yield. carbo
