介绍了二烷基硒化合物1的选择性合成研究。克服硒化物 (R-Se-R) 和/或多硒化物 (R-Se n -R; n ≥ 2) 的复杂性和难度,我们旨在优化制备硒化钠 (Na 2 Se)耐受性的反应条件通过用NaBH 4还原Se ,然后通过随后用烷基卤化物(RX)处理获得的硒化钠来实现二烷基硒化物1的选择性合成。因此,各种二烷基硒化物1以良好至中等的产率有效合成。还描述了对反应途径和溶剂研究的调查。
unexpected amount of Ph−Se bond cleavage (35% in n-hexane at 248 nm) during photolysis. Solvent viscosity, wavelength of light, and the structure of alkyl substituents were the major factors that controlled Ph−Se bond cleavage. The ratio of Ph−Se bond cleavage decreased with increasing solvent viscosity and laser wavelength. The effect of alkyl substituents on the ratio of bond cleavages, Ph−Se/total C−Se

dialkyl selenide compounds 1 were presented. Overcoming the complexity and difficulty of selenides (R-Se-R) and/or multiselenides (R-Sen-R; n ≥ 2), we aimed to optimize the reaction condition for the tolerable preparation of sodium selenide (Na2Se) by reducing Se with NaBH4, and then to achieve selective syntheses of dialkyl selenides 1 by subsequently treating the obtained sodium selenide with alkyl
