摘要：

The syn/anticonformational equilibrium of o-substituted benzaldehyde chromium tricarbonyl complexes was studied by CD and H-1 NMR (NOE). The preferred conformation of the o-methyl-, o-methoxy-, and o-iodobenzaldehyde complexes is anti, while those of the o-trimethyltin and o-trimethylsilyl benzaldehyde complexes is syn. The optical rotation values of (o-trimethylsilyl benzaldehyde)Cr(CO)(3) ((1S)-2d) vary from -174 (in ethanol) to +108 (in chloroform).
