摘要：

Molecular (N,S) aminothiols R(CH2)(3)NH(CH2)(2)SH (1), R(CH2)(3)NH(CH2CHMe)SH (2), R(CH2)(3)NH(CH2)(2)S(CH2)(2)SH (3), R(CH2)(3)NH(CH2CHMe)S(CH2CHMe)SH (4) and R(CH2)(3)N[(CH2)(2)H](2) (5) [R = (EtO)(3)Si] have been prepared by a one step reaction of olefin sulfide on aminopropyltriethoxysilane and characterised by physicochemical methods; the grafting of 1 on silica is reported.
