通过将相应的环己基甲醇与香豆素衍生的芳基溴化物或碘化物直接偶联,合成了从紫ster中分离出的两种香豆素,这是一个非常困难的醚化反应,这是由于甲醇周围的空间拥塞过多以及使芳基卤化物的反应性低而造成的。许多看似可行的协议。因此,首次获得了这些化合物的明确1 H和13 C NMR数据。先前报告中1 H和13 C NMR数据的不确定性和错误也分别消除和揭示。

A powerful difluoromethylating reagent [Ph4P]+[Cu(CF2H)2]− that was able to difluoromethylate a variety of aryl and alkyl electrophiles was developed. In the presence of an oxidant, complex 2 also reacted with various lithium nbutyl arylboronic acid pinacol esters, alkyne and heteroarene. Moreover, complex 2 could transmetalate the difluoromethyl reagent to other metals such as [Ph4P]+[Cu(Cl2)]− and

The present polymeric materials can be patterned with relatively low photo-exposure energies and are thermally stable, mechanically robust, resist water penetration, and show good adhesion to metal oxides, metals, metal alloys, as well as organic materials. In addition, they can be solution-processed (e.g., by spin-coating), and can exhibit good chemical (e.g., solvent and etchant) resistance in the cured form.
