Compound Q&A
How is 2,6-Bis(2,4,6-triisopropylphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-ol 4-oxide (CAS: 874948-63-7) typically synthesized?
Answer
![2,6-Bis(2,4,6-triisopropylphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-ol 4-oxide](https://static.chemtradehub.com/structs/874/874948-63-7-d270.webp "2,6-Bis(2,4,6-triisopropylphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-ol 4-oxide")
The compound is typically synthesized through a multistep process involving the reaction of 2,6-di-tert-butyl-4-methylphenyl diphenylphosphine oxide with 2,6-di-tert-butyl-4-methylphenyl 4-oxo-1,3,2-dioxaphospholane. The synthesis involves the use of a catalytic amount of a Lewis acid, and the product is isolated by recrystallization from organic solvents. The yield is around 80-85% with good regioselectivity.
