M-Methylacetophenone

A //-hexane solution containing ///-xylene and spread as a thin film (4 mm) on cold water (10 °C) was irradiated by a mercury medium pressure lamp. In 3 h, 25% of the ///-xylene photooxidized into ///-methylbenzaldehyde, ///-benzyl alcohol, ///-benzoic acid, and m methylacetophenone (Moza and Feicht, 1989). [Pg.1157]

Lithiation study of xylenes indicates a much higher reactivity of the meta isomer (m- o >p-). On the other hand, only the meta isomer of methylacetophenone... [Pg.82]

Verghese has published a review about this class. Authentically naturally occurring m-menthanes are m-thymol (687, R = H) and its methyl ether 687 (R = Me), isolated from various Calea species as well as the isobutyl ether 687 (R = iBu) from Athrixia elata. Paknikar has synthesized 687 (R = H) by Grignard reaction of 2-hydroxy-5-methylacetophenone. ... [Pg.391]

The stages in the production of salbutamol are as follows the starting material is diacetate , 4 -hydroxy-3 -hydroxymethylacetophenone diacetate which is a waxy powder and a series of reactions produces in turn glycyl compound , 2-(iV-benzyl-A -/ r/-butylamino)-4 -hydroxy-3 -hydroxymethylacetophenone diacetate, then benzyl compound , 2-(iV-benzyl-/er/-butylamine)-4 -hydroxy-3 -hydroxy-methylacetophenone hydrochloride and finally salbutamol, a-/ r/-butyla-minomethyl-4-hydroxy-m-xylene-a,a -dioL... [Pg.176]
