osmium-catalyzed dihydroxylation has uncovered that electron-deficient olefins are converted into the corresponding diols much more efficiently when the pH of the reaction medium is maintained on the acidic side. Further studies have identified citric acid as the additive of choice, for it allows preparation of very pure diols in yields generally exceeding 90%. As described here, a much wider range of olefin classes

The present invention relates to modifiable linear polyunsaturated polymers and processes for preparing the same comprising reacting solely at least one bifunctional nucleophilic compound with at least one α-functional unsaturated monomer. The at least one bifunctional nucleophilic compound of the invention comprises two nucleophiles independently selected from the group consisting of C, N, O, S and Se. The at least one α-functional unsaturated monomer of the invention comprises two leaving groups L
1
and L
2
, wherein at least one of the leaving groups L
1
and L
2
of the at least one α-functional unsaturated monomer is part of the nonaromatic unsaturated structure C═C—C
α
-L. The double bond of said α-functional unsaturated monomer is maintained in the polyunsaturated polymer.
本发明涉及可改性线性多不饱和聚合物以及制备该聚合物的工艺,包括仅使至少一种双官能团亲核化合物与至少一种α官能团不饱和单体反应。本发明的至少一种双官能团亲核化合物包括两个独立选自 C、N、O、S 和 Se 组的亲核物。本发明的至少一种 α-官能团不饱和单体包括两个离去基团 L
1
和 L
2
其中至少一个离去基团 L
1
和 L
2
的至少一个离去基团 L 1 和 L 2 是非芳香族不饱和结构 C═C-C
α
-L.所述 α-官能团不饱和单体的双键保留在多不饱和聚合物中。
