W is the peak of water protons. (Reprinted with permission from ref. 72, Copyright 2000 American Chemical Society.)...

As in the case of pure p-cresol, a number of important organic chemicals are now S3mthesized from m-cresol. For instance, synthetic pyrethroids from m-phenoxy benzalde-hyde obtained from m-cresol are already produced by Sumitomo Chemical Co. of Japan. Similarly 2,3,6-trimethyl phenol (TMP), a vital raw material for manufacture of synthetic Vitamin-E, the fastest growing vitamin, is now made from m-cresol by a number of companies. Slowly, but steadily, m-cresol network is expanding.

The approved way of preparing the cyanohydrine 299 by the addition of prussic acid is no problem in the case of 3-phenoxybenzaldehyde 280, The use of acetone cyanhydrine as a source of prussic acid [629] seems to be advantageous. In order to circumvent the aldehyde 280, an alternative route from the trimethyl-3-phenoxy benzylammonium salt 296 and the corresponding 3-phenoxybenzyl nitrile 297 [630] was proposed, in which oxalic ester condensation and subsequent brominative degradation of this whole group was applied (Reaction scheme 211). This procedure supposedly yields a particularly pure a-bromobenzyl cyanide 298 [631].
