The betaines formed by attack of the tervalent phosphorus compounds R2PX (X = NCO, NCS, or CH:CH2) on the oxygen atom of hexafluoroacetone (HFA) cyclise to give ylides which react further with HFA to give bicyclic phosphoranes. A 1,3,2-oxazaphosphetan is formed from the phosphoramidite (PhO)2P·NHPh and HFA.
通过三价磷化合物R 2 PX(X = NCO,NCS或CH:CH 2)在六氟丙酮(HFA)环化的氧原子上的攻击而形成的甜菜碱,可生成与IFA进一步反应生成双环磷烷的酰化物。由亚磷酰胺(PhO)2 P·NHPh和HFA形成1,3,2-氧杂磷鎓。
