查询词典 reflux

The macro conjugated molecule fluorene derivative has 2, 3, 6, 7-tetraamino-9, 9'-dialkyl fluorene as a raw material which is added to an organic solvent respectively together with phenanthrenequinone, acenaphthene quinone or bis-carbonyl pyrene derivatives and strong base; under the protection of inert gas, reflux reaction is carried out to the materials, so as to prepare a series of trapezoidal conjugated molecules containing fluorine structures.

本发明涉及一类含大共轭分子的芴衍生物及其制备方法，大共轭分子芴衍生物是将原料2，3，6，7-四氨基-9，9'-二烷基芴，分别与菲醌、苊醌或二羰基芘的衍生物以及强碱加入到有机溶剂中，在惰性气体的保护下，回流反应制得一系列含有芴结构的梯形共轭分子。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。
