  Novel photosensitizers for the E/Z-isomerization of trienes. Part 1. Syntheses and application

  摘要：

  Uranine and its thioxanthene and selenoxanthene analogues, as well as the disodium salts of o-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzenesulphonic acid and its thioxanthene and selenoxanthene analogues, show different photosensitizer properties in the E/Z-isomerization of trienes. This has been verified by applying them to the technically useful conversion of tachysterol into previtamin D. The syntheses of the novel photosensitizers with thioxanthene and selenoxanthene moieties are also described.

  二氧化硒促进芳基肼和苯胺的二氮挤出/直接硒化

  摘要：

  已经开发出一种新颖，有效，经济的策略，用于使用SeO2将芳基肼偶联并直接硒化成硒化物。我们的方法采用SeO2作为硒源，与肼作为偶合反应物，通过二氮挤压生成硒化物。该试剂还有助于通过C–H官能化反应以高收率生成ArSe取代的苯胺衍生物。还进行了该方法在克量表中的应用。

• Microwave-assisted Cu2O-catalyzed one-pot synthesis of symmetrical diaryl selenides from elemental selenium

  日期：2013.8

  A novel and simple microwave-assisted one-pot protocol to prepare symmetrical diary] selenides has been developed. A cross-coupling reaction between aryl iodide and elemental selenium takes place in the presence of KOH and a catalytic amount of Cu2O/NH2CH2CH2NH2, leading to C-Se bond formation. The reactions are highly efficient with a reaction time of 1 h under microwave irradiation and yields from 50% to 90%. Published by Elsevier Ltd.
• Synthesis and Reactivity of Dibenzoselenacycloheptynes

  日期：2013.6.21

  Dibenzoselenacycloheptynes were prepared in three steps from commercially available reagents and trapped in situ with benzyl azide to form the corresponding triazoles. Surprisingly, the dibenzoselenacycloheptynes also abstracted hydrogen atoms from solvents such as THF or toluene, forming dibenzoselenacycloheptene products. These alkenyl compounds arise from a hydrogen transfer reaction from solvent to the unisolable Intermediate, and we postulate that the reaction proceeds via a radical mechanism originating from the strained alkynyl bond that has unusually high radical character.

  The selenoxides forming 9-oxoselenoxanthenium and triaryl selenonium hexafluorophosphates via interaction with heptyl phenyl ether and anisole in the MeSO3H-P2O5 mixture followed by treatment with KPF6 have been obtained via selenoxantene-9-one and diphenyl selenide derivatives oxidation with m-chloroperoxybenzoic acid or hydrogen peroxide.
