Vibrational spectra and structure of dimethyl diselenide and dimethyl diselenide-d6
Green, William H.,Harvey, Albert B.
, p. 3586 - 3595 (1968)
The vibrational behavior of the dimethyl diselenide and dimethyl diselenide-rfe molecules has been studied in the infrared region (4000-70 cm-1) and by Raman shifts (4000-50 cm-1). The molecule has been found to belong to point group C2. The fundamental vibrations, with the exception of the methyl torsions, have been assigned and supported by a normal-coordinate analysis.

Paragraph 0032-0036, (2021/11/21)
The method comprises the following steps: taking the compound represented by the formula (II) as a reaction raw material and I as a reaction raw material, and taking water or ethanol as a solvent under Se 40 - 75 °C conditions to obtain the reaction liquid to obtain the dialkyl diselenium ether compound shown in the formula (II KOH). The reaction is short in reaction time, does not need a metal catalyst, uses water as a solvent, and belongs to green and environment-friendly reaction. Economy, high efficiency, green, environmental protection.

A non-oxidant and metal-free strategy for synthesizing iso-coumarin by using a continuous electrochemical microreactor to initiate an oxidative cyclization reaction of o-(1-alkynyl) benzoate and radicals. This efficient and clean continuous electrosynthesis method not only avoids the complicated gas protection operation and production of by-products in the batch processes, but also help to overcome the difficulty that batch metal catalysis and electrocatalysis are difficult to scale up, and has the potential for pilot-scale experiment.
Simultaneous Construction of C?Se And C?S Bonds via the Visible-Light-Mediated Multicomponent Cascade Reaction of Diselenides, Alkynes, and SO2

A visible-light mediated multicomponent cascade reaction of diselenides, alkynes, and sulfur dioxide was developed, in which multiple C?Se and C?S bonds were constructed, and unexpected β-sulfonylvinylselane compounds were generated with high selectivity for E configuration. β-Sulfonylvinylselane transformation into 1,4-oxathiine-4,4-dioxide and sulfonylethyne derivates was then investigated. A plausible mechanism involving a selenium radical-initiated cascade reaction and sulfur dioxide insertion was proposed.
