The author of 《Highly atom-economical, catalyst-free, and solvent-free phosphorylation of chalcogenides》 were Choudhary, Rakhee; Singh, Pratibha; Bai, Rekha; Sharma, Mahesh C.; Badsara, Satpal Singh. And the article was published in Organic & Biomolecular Chemistry in 2019. Synthetic Route of C12H10S2 The author mentioned the following in the article:
Silica gel promoted, catalyst-free and solvent-free S-P, Se-P and Te-P bond formations are described, giving chalcogen-substituted phosphorus esters. A variety of disulfides coupled with diarylphosphine oxides provide the corresponding phosphinothioates in excellent yields. For the first time, diselenides and ditellurides reacted with dialkyl phosphites under catalyst-free conditions to provide the corresponding phosphoroselenoates and phosphorotelluroates, resp., in good to excellent yields. The results came from multiple reactions, including the reaction of 1,2-Diphenyldisulfane(cas: 882-33-7Synthetic Route of C12H10S2)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. Synthetic Route of C12H10S2 They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however.
