Fine Organic Synthesis by Anisotropic Control of Reactive Intermediates

(1)合成了二次生色团与亚甲基桥相连的四苯基孔膦钠锑配合物。在卟啉环的照射下，通过电子转移使卟啉环的荧光猝灭。为了提高光胺化反应的效率，我们将1，3，5-三苯基苯和2，2‘-二烷氧基萘作为1，2-二芳基环丙烷和苯并环庚烯的氧化还原光敏化反应的敏化剂。(3)为了发展可见光诱导氯苯酚的光脱氯反应，我们研究了硅胶负载的四苯基膦锑络合物在水溶液中的光反应。(4)研究了手性苯基二芳基环丙烷和苯并环庚烯的光敏化反应。在(+)-和(-)-异构体中存在不同的反应行为。(5)通过亚甲基链与对氰基苯甲酸酯基团相连的烷氧基萘的激基络合物发射，建立了溶剂参数。

(1) We synthesized tetaraphenylporophynatoantimony complexes having second chromophore linked with methylene bridge on an axial ligands. Upon the irradiation of porphyrin ring, the fluorescence quenching of the porphyrin ring through electron tranfer. On the other hand, the irradiation of second chromophoire induced the fluorescence quenching of the second chromophore through both electron and energy tranfers.(2) In order to enhance the efficiency of the photoamination, we applied to redox-photosensiitization using 1,3,5-triphenylbenzene and 2,2'-dialkoxynaphthalene as a sensitizer to the photoamination of 1,2-diarylcyclopropanes and benzozycloheptene.(3) In order to develop the visible-light induced photodeclorination of chlorophenols, we investigated the photoreaction of the silica-gel supported teteraphenylporphynatoantimony complex in aqueous solution.(4) In order to elucidate the aymmetric recognization in the exicited state, the inclusion of the chiral benzylidene tatartrates into beta-cyclodextrin has been investigated. The behavior of the incusion were different in (+)-and (-)-isomers.(5) We have developed the solvent parameter based on the exiciplex emission of alkoxynaphthalenes linked with the p-cyanobenzoate group by methylene chain.
