低价钛引起的芳基二硫醚与α,β-不饱和酯(腈)的反应
The Reaction of Diaryl Disulfide with α,β - Unsaturated Esters or α,β - Unsaturated Nitriles Induced by Low - valent Titanium
【摘要】 芳香族二硫醚在低价钛试剂作用下,S-S键还原断裂成芳硫负离子,再与α,β-不饱和酯(腈)发生Michael加成反应,得到β-硫代酸酯(腈)。
【Abstract】 The S - S bond in diaryl disulfide were reduced by low - valent titanium reagent to produce titanium arylsulfolate. The new sulfolate anion reacted with α,β- unsaturated esters or α,β-unsaturated nitriles to give β - sulfo esters and β- sulfo nitriles, respectively.
