摘要：

C-13 NMR spectra of several eta-6-arenetricarbonylchromium complexes of phenylacetylene and phenyltrimethylsilylacetylene have been interpreted. The complexing chemical shifts (CCS) observed for alpha and beta acetylenic carbons suggest the existence of a direct interaction between the metal atom and pi-electron system of the ethynyl substituent. The overall complexing effect is of the electron-withdrawing type which was confirmed by delta(Si-29), 2J(CH) and IR data. Some observations concerning synthesis of the investigated complexes have been also reported.
