How is 2,4-Dichloro-1-(2-nitrovinyl)benzene (CAS: 18984-21-9) typically synthesized?

2,4-Dichloro-1-(2-nitrovinyl)benzene (CAS: 18984-21-9) is typically synthesized through a multi-step process involving the nitration of 2,4-dichlorobenzene followed by the vinyl chloride addition. The process often requires the use of a catalyst and involves careful control of reaction conditions to achieve high selectivity and yield. Detailed procedures are typically found in organic chemistry literature and can be adapted for laboratory-scale production.
