Straightforward Synthesis of Bifunctional Phosphorus Phenols via Phosphination of In Situ Generated o -Quinone Methides.
MOLECULES(2018)
摘要
An efficient and practical approach towards bifunctional phosphorus phenols has been developed through a reaction of diphenylphosphine oxide and the o-quinone methides in situ generated from 2-tosylalkyl phenols under basic conditions. This protocol features simple experimental procedures under mild conditions and is easily scaled up. With this method, a variety of diarylmethyl phosphine oxides can be produced with up to 92% yield.
