Base-promoted proton abstraction from π-(N-tert-butyldimethylsilyl-N-methylaniline) chromium tricarbonyl (3) took place predominantly at the meta position and variously meta-substituted N-methylacetanilides 4 were obtained after reactions with electrophiles followed by oxidative decomplexation and N-acetylation. Application of the present method to variously N, N-disubstituted anilines 5 and phenols 7 was then examined and the corresponding meta substituted anilines 6 and phenol 9 were obtained.
