How is 2,4-Decadienal (CAS: 2363-88-4) typically synthesized?

2,4-Decadienal can be synthesized via the hydroformylation of 2-buten-4-one followed by hydrolysis. Alternatively, it can be prepared by the hydroformylation of 2-buten-4-ol. The reaction uses rhodium catalysts with a cobalt or iron-based co-catalyst, typically requiring high pressure and temperature conditions. The yield is around 80-90%, and the product is usually purified by distillation.
