  still in its infancy. We demonstrate herein transition-metal-free decarboxylative C(sp3)–X bond formation enabled by the photochemical activity of the NHPI ester–NaI–NHC complex, giving primary C(sp3)–(N)phth, secondary C(sp3)–I, or tertiary C(sp3)–(meta C)phth coupling products. The primary C(sp3)–(N)phth coupling offers convenient access to primary amines.

  尽管N-羟基邻苯二甲酰亚胺（NHPI）酯已成为一种强大的试剂，可作为各种C-C键形成的烷基自由基来源，但相应的C（sp 3）-N键形成仍处于起步阶段。我们在这里证明了NHPI酯-NaI-NHC复合物的光化学活性使无过渡金属的脱羧C（sp 3）-X键形成，从而形成了一级C（sp 3）-（N）phth，二级C（sp）3）–I或三次C（sp 3）–（元C）phth偶联产物。伯C（sp 3）–（N）phth偶联为伯胺提供了便捷的通道。

  The present invention provided a norbornene compound with cross-linkable groups and their derivative polymers, wherein said cross-linkable groups were olefin or epoxy groups. Norbornene polymers with cross-linkable side chain and their block copolymers as well as modified derivatives were prepared via living ring-open metathesis polymerization method. The resulting polymers with excellent solubility and optic properties had narrow molecular weight distribution, well-controlled molecular weight, small refraction ration and high transparency. They were also suitable for preparing hybrid materials with high thermal stability and chemical resistance.

  [3,3′-Co(8-C5H10O-1,2-C2B9H10)(1′,2′-C2B9H11)] (2) was synthesized by reaction of the caesium salt of [Co(C2B9H11)2]− with dimethyl sulfate in the presence of sulfuric acid as catalyst and tetrahydropyrane as solvent; the zwitterionic compound (2) yielded [3,3′-Co(8-C4H4N-(CH2)5-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (6), [3,3′-Co(8-C8H6N-(CH2)5-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (7), and [3,3′-Co(8-C12H8N-(CH2)5-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (8) through the nucleophilic addition of potassium pyrrolyl, indolyl and carbazolyl, respectively. The nucleophilic addition of the same salts on [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] (1) yielded, respectively, [3,3′-Co(8-C4H4N-(CH2)2-O-(CH2)2-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (3), [3,3′-Co(8-C8H6N-(CH2)2-O-(CH2)2-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (4), and [3,3′-Co(8-C12H8N-(CH2)2-O-(CH2)2-O-1,2-C2B9H10)(1′,2′-C2B9H11)]− (5). All these products were isolated, purified and characterized by means of 1H, 1H11B}, 11B, 11B1H} and 13C1H}-NMR and IR spectroscopies, MS MALDI-TOF spectrometry and elemental analysis. The behavior of the exo-cluster chain has been proven to be, in solution, very similar irrespective of the nucleophilic agent introduced into the molecule. The X-ray diffraction study of the potassium salt of 3 has proven the evidence of B–H⋯K+ interactions in solid state. The 1H11B}-NMR spectra recorded in the range between 37 °C and −58 °C have proven the presence of the three intramolecular B–H⋯K+ interactions in solution. The possible role of [Co(C2B9H11)2]− as a doping agent in conducting organic polymers is also discussed.
