5-Halo-2,3,4,6-tetramethyl- and 6-halo-2,3,4,5-tetramethylbenzyl nitrate were the principal products. 4-Halo-2,3,5,6-tetramethylbenzyl nitrate was never formed in any significant amount. The orientation was consistent with the previously suggested mechanistic scheme. PMR spectral data for nine halotetramethylbenzyl chlorides and nitrates have been presented.

The Jacobsenreaction of monochlorotetramethylbenzenes was found to yield dichloroheptamethyldiphenylmethanes as by-product. Their indefinite structure proof was made on spectroscopy and synthesis. 1H NMR spectra for a variety of polymethyldiphenylmethanes and their chlorine derivatives were determined.
