Process for the preparation of aminobenzyl vinyl sulfone and aminobenzyl alkyl sulfone isomer mixtures |
| abstract |
Prepn. of aminobenzyl vinyl sulphone and aminobenzyl alkyl sulphone isomer mixts. of formula (I) or a salt of these comprises nitrating a benzyl (vinyl or alkyl) sulphone of formula (II) to a nitro deriv. of formula (III) and reducing (III) to (I). Z = CH2CH2X or CH=CH2; X = OH, OSO3H, Cl, Br, OCOCH3, OPO3H2 or S2O3H. Also claimed is the prodn. of a reactive dye using the isomer mixt. of (I). |
