How is Cyhalothrin solution (CAS: 68085-85-8) typically synthesized?

Cyhalothrin solution (CAS: 68085-85-8) is synthesized through a multi-step process involving chlorination of a cyano compound followed by conversion to the alcohol and subsequent epoxidation. The reaction requires the use of Lewis acids as catalysts and typically achieves a yield of around 85%. The process is selective and involves careful control of reaction conditions to ensure high quality and purity.
