Abstract
Silylation of diazoacetic esters with (t-Bu)(2)Si(Cl)OTf or Ph(t-Bu)Si(Cl)O Tf (Tf = SO2CF3) yields alpha(chrorosilyl)-alpha-diazoacetates 3a-d, which can be converted into azidosilyl- (7), isocyanatosilyl- (8), and isothiocya natosilyl- (9) substituted diazoacetates. Acid-catalyzed hydrolysis of 8a o r 9a generates (hydroxysilyl)diazoacetate 10. (Allylaminosilyl)diazoacetate s 12a,b can be prepared from diisopropylsilyl bis(triflate) by successive t reatment with diazoacetic esters and allylamine.
