DIPHENYL DISULFIDE C화학적 특성, 용도, 생산
화학적 성질
White to light yellow crystal.출처
Naturally occurring phytoalexin-like substan용도
Diphenyl disulfide is one of the most popular organic disulfides used in organic synthesis. It is used as a reagent for the α-phenylsulfenylation of carbonyl compounds. It participates in hydrothiolation of alkynes via amine-mediated single electron transfer mechanism. It is the hydrolysis product of dyfonate.제조 방법
By heating and passing a stream of air over an ammoniacal solution of thiophenol.Purification Methods
Crystallise the disulfide from MeOH. [Alberti et al. J Am Chem Soc 108 3024 1986]. Also crystallise it repeatedly from hot Et2O, then dry it in a vacuum at 30o over P2O5, fuse it under N2 and re-dry it; the whole procedure being repeated, with a final drying under a vacuum for 24hours. Alternatively, recrystallise it from hexane/EtOH solution. [Burkey & Griller J Am Chem Soc 107 246 1985, Beilstein 6 H 323, 6 IV 1560.]DIPHENYL DISULFIDE 준비 용품 및 원자재
