Paragraph 0056; 0059; 0060; 0061, (2018/07/30)
The invention relates to a large-tension oxygen substituted quaternary phosphor derivative as an organic phosphorus reagent. A chemical structural formula of the above compound is shown in the specification. The compound takes pentalyl propylene as a raw material, under catalysis of Lewis acid, the pentalyl propylene and trivalent phosphor are subjected to a reaction to generate phosphorus chlorine salt, the phosphorus chlorine salt and a hydroxyl compound are subjected to nucleophilic substitution to form a phosphor oxygen bond, and the large-tension oxygen substituted quaternary phosphor derivative can be obtained. An oxygen substituted quaternary phosphor ring structure is introduced and can be used as an efficient and practical oxygen phosphor reagent, the application scope is wide, and the oxygen substituted quaternary phosphor ring structure has an irreplaceable effect in many specific reactions participated with phosphor. The large-tension oxygen substituted quaternary phosphorderivative with a novel structure is synthesized; and a novel synthesis route of the large-tension oxygen substituted quaternary phosphor derivative is provided, the synthesis route is a novel methodwhich has the advantages of less step and high yield, at the same time, the effective application of the large-tension oxygen substituted quaternary phosphor derivative can be successfully achieved, and an intramolecular aza Wittig reaction is effectively catalyzed.
