  of carbonyl compounds has been developed. When carbonyl compounds were allowed to react with trimethylsilyl phenylselenide and tributylstannyl hydride in the presence of a catalytic amount of AIBN as the radical initiator, hydrosilylation of the carbonyl compounds efficiently proceeded to give the corresponding silyl ethers in moderate to good yields. In the absence of carbonyl compounds, the triethylsilyl

  已经开发出一种用于羰基化合物的氢化硅烷化的新方法。当在催化量的AIBN作为自由基引发剂的存在下使羰基化合物与三甲基甲硅烷基苯基硒化物和三丁基锡烷基氢化物反应时，羰基化合物的氢化硅烷化有效地进行，以中等至良好的产率得到了相应的甲硅烷基醚。在不存在羰基化合物的情况下，通过PhSeSiEt（3）与Bu（3）SnH的反应获得氢化三乙基甲硅烷基。尽管在自由基条件下在苯甲醛存在下用三丁基锡锡氢化物处理了三丁基锗烷基苯硒化物而不是PhSeSiMe（3），但未获得氢化麦芽酰化的产物，并且主要形成了三丁基锗锡氢化物。

  The silylation/germylation of several disulfides/diselenides has been established by using commercially available ruthenium catalyst. As a result, several silylthioethers and their germanium and selenium analogs have been synthesized. Notably, the obtained thiosilanes were subsequently utilized in nucleophilic aromatic substitution reaction, leading to unsymmetrical sulfides.

  通过使用市售的钌催化剂已经建立了几种二硫化物/二硒化物的甲硅烷基化/胚芽化。结果，合成了几种甲硅烷基硫醚及其锗和硒类似物。值得注意的是，得到的硫硅烷随后被用于亲核芳族取代反应，导致硫化物不对称。

  The investigation presented in this paper explores the mechanistic aspects and synthetic potentials of PET promoted reductive activation of selenosilane la to its radical anion la(-.). PET activation of la is achieved through a photosystem comprising a light-absorbing electron-rich aromatic (ERA), such as DMN or DMA, as an electron donor and ascorbic acid as a co-oxidant. The evidence for the ET from excited singlet states of DMN as well as DMA to la is suggested by estimating negative Delta G(et) (-51 and -43.46 kcal mol(-1), respectively) values and nearly diffusion-controlled fluorescence quenching rate constants (k(q)TR) 0.36 x 10(10) M-1 s(-1) and 0.28 x 10(10) M-1 s(-1), respectively, from time-resolved fluorescence quenching study. The transient absorption spectra of DMN.+, DMA(.+), and la(.-) are obtained initially by pulse radiolysis in order to correlate the time-resolved absorption spectral data. Laser flash photolysis studies in the nanosecond time domain have confirmed the generation of la(.-), DMN.+, and DMA(.+), supporting the participation of the triplet state of DMN or DMA in the ET reaction. Mesolytic cleavage of 1a(.-) produced a silyl radical and a phenyl selenide anion. The preparative PET activation of la in acetonitrile in the presence of DMN or DMA leads to the formation of 5 and 6, confirming the fragmentation pattern of la(.-). The overall ET rate constants (K-r(DMN) = 0.99 x 10(10) M-1 s(-1) and k(r)(DMA) = 1.62 x 10(10) M-1 s(-1)) and limiting quantum yields (phi(lim)DMN) = 0.034 and phi(lim)(DMA) = 0.12) are estimated from the inverse plot (1/[la] vs 1/phi(dis)) Obtained by measuring the dependence of photodissociation quantum yields of la at its maximum concentration in the presence of DMN or DMA. Silicon-centered radical species generated from the mesolysis of la(.-) are utilized for initiating a radical reaction by the abstraction of halogen atom from -C-X (X = Cl, Br) bonds, while PhSe- terminates the radical sequences via PhSeSePh. This concept is successfully applied for the bimolecular group transfer (BMGT) radical reactions and intermolecular radical chain addition reactions.
