Abstract
A process for the production of a styrene compound is provided. The process comprises reacting a Grignard reagent prepared from a tertiary butoxyphenyl halide with a vinyl halide in the presence of a catalyst, wherein the catalyst is at least one member selected from the group consisting of manganese catalyst, iron catalyst, cobalt catalyst and rhodium catalyst. The process overcomes the problems involved in the prior art, and is economical and safe. The styrene compound by the process is free from biphenyl.
Claims14
A process for the production of a styrene compound which comprises reacting a Grignard reagent prepared from a tertiary butoxyphenyl halide represented by the following formula (I):
- wherein X represents a halogen atom, with a vinyl halide in the presence of a catalyst, wherein said catalyst is at least one member selected from the group consisting of a manganese catalyst, an iron catalyst, a cobalt catalyst and a rhodium catalyst.
A process for the production of a styrene compound which comprises reacting a Grignard reagent prepared from an aromatic halogen compound with a vinyl halide in the presence of a catalyst, wherein said catalyst is at least one member selected from the group consisting of a manganese catalyst and a rhodium catalyst.
