An environmental protection reactive dyestuff of the following formula (I) is disclosed,
wherein R
1
, R
2
, D, M are defined as in the specification. The dyestuff of the invention is distinguished by a high fixation and a very good build-up. It is distinguished also by a green environmental protection and a low salt, a low base, a high exhaustion, non-contain heavy metal and halogen atoms, and it has fiber-reactive properties and is very highly suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide containing fibers such as wool and nylon.
The present invention encompasses a process for preparing arylolefins by reacting one or more arylamines with one or more organic nitrites, in the presence of one or more olefins which bear at least one hydrogen atom on the double bond and in the presence of acid and in the presence of palladium or one or more palladium compounds.
