  The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.

  Abstract Wurtz-type radical coupling of a variety of allylic and benzylic bromides was observed on irradiation with dimanganese decacarbonyl in excellent yield (77-99%). Efficient cross-coupling of two different bromides was also readily achieved.

  Homo-coupling of alkyl halides in aqueous media can be mediated by manganese/cupric chloride to give the dimerisation products in good yield. Cross-coupling can also be controlled to give the desired product.

  Cobalt(III) ammine complexes coordinated to carboxylic acids are classic examples showing photoredox reactions originating from the ligand to metal charge transfer excited states. Cobalt(III) pentaammine complexes coordinated to unsaturated carboxylic acids as ligands were synthesized and characterized by spectroscopic methods. The photolysis of these complexes produces a carboxylate free radical.

  与羧酸配位的钴（III）胺配合物是经典实例，显示出光氧化还原反应源自配体到金属电荷转移的激发态。合成了以不饱和羧酸为配体配位的五胺合钴（III）配合物，并通过光谱法对其进行了表征。这些配合物的光解产生羧酸根自由基。该自由基进行进一步转化以形成有机光产物。用光谱方法表征有机光产物。详细检查了有机光产物分解产物的性质。还确定了量子产率。光化学反应具有从不饱和酸的脱羧反应产生新化合物的潜力，这显示出有趣的反应途径。

  A method of producing a highly stable packaging substrate in which are provided a first precursor having a first backbone and a first ethynyl group, and a second precursor having a second backbone and a second ethynyl group. Furthermore provided is a crosslinker having a first and a second reactive group. The first precursor, the second precursor, the crosslinker, and a solvent are applied onto a surface to form an electrically insulating layer. The first ethynyl group is reacted with the first reactive group in a first carbon-carbon bond formation reaction and the second ethynyl group is reacted with the second reactive group in a second carbon-carbon bond formation reaction to crosslink the first backbone with the second backbone, thereby forming the packaging substrate. The solvent is removed in a further step.
