Preparation of 1,3-diphenylselenophenotetraazaporphyrinato ruthenium(II) Bis(4-methylpyridine) by the reaction of 3,4-dicyano-2,5-diphenylselenophene and phthalonitrile: Its optical and electrochemical properties

2,5-Diphenylselenophene (2a) was treated with bromine and then copper(I) cyanide to produce 3,4-dicyano-2,5-diphenylselenophene (4). Compound 4 was mixed with phthalonitrile, and the mixture was reacted with ruthenium(III) trichloride and 4-methylpyridine in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in refluxed 2-ethoxyethanol to give 1,3-diphenylselenophenotetraazaporphyrinato ruthenium(II) bis(4-methylpyridine) (6). The structure of 6 was determined by 1H NMR and fast atom bombardment mass spectrometry (FABMS). In the 1H NMR spectrum, the signals of 4-methylpyridine coordinating to the central ruthenium atom were observed at a higher magnetic field than those of free 4-methylpyridine itself but at a lower magnetic field than those of phthaocyaninato ruthenium(II) bis(4-methylpyridine) (7). The 77Se NMR spectrum of 6 showed one singlet peak at δ = 759.5 ppm, which is a lower magnetic field than those of 2a and 4. The Q band absorption of 6 (λmax = 660 nm) lies at a longer wavelength than does that of 7. Oxidation and reduction potentials of 6 were measured with cyclic voltammetry using Ag/AgNO3 as a reference electrode.
Carbon-sulfur bond formation from 2-halochalcogenophenes via copper catalyzed thiol cross-coupling
Zeni, Gilson
, p. 2647 - 2651 (2007/10/03)
We present herein our results of the thiol coupling reaction of 2-halochalcogenophenes with Cu(I) and establish the first route to prepare (2-sulfides)-chalcogenophenes in good yields. The reaction performed with both electron donating and electron withdrawing substituents on thiol in the absence of any supplementary additives. In addition, the reaction proceeded cleanly under mild reaction conditions and was sensitive to nature of catalyst, base, and solvent.
Efficient synthesis of 2-iodo and 2-dicyanomethyl derivatives of thiophene, selenophene, tellurophene, and thieno[3,2-b]thiophene
Takahashi, Kazuko,Tarutani, Shinji
, p. 1927 - 1935 (2007/10/03)
An effective synthesis of 2-iodothiophene, 2-iodotellurophene, and 2-iodothieno[3,2-b]thiophene and a Pd-catalyzed carbon-carbon coupling reaction of these iodo derivatives as well as 2-iodoselenophene with malononitrile affording novel thienyl-, tellurienyl-, thieno[3,2-b]thienyl-, and selenienybnalononitrile are described. These heteroarylmalononitriles are important synthons for the preparation of 2-dicyanomethylene-2,5-dihydroheterophene chromophores.
