Abstract: The reaction between ferrocenylmethylaminoalcohols and chlorosilanes gave 12 compounds of ferrocenylmethylaminoalkoxy silanes in one-step method and in relatively good yield.The synthetic method and relationship between the water sensitivity and structures of the compounds were investigated.The experimental results show that both of the aminoalcohols FcCH₂NHCH(R')CH(R″)OH(Fc=C₅H₅FeC₅H₄,R'=H,C₂H₅;R″=H,CH₃)and chlorosilanes R(CH₃)₂SCl(R=CH₃,C₂H₅,n-C₃H₇,n-C₄H₉)have influnce on the reaction.The more bulky R,R'and R″,the smaller the reaction rate.The title compounds FcCH₂NHCH(R')CH(R″)OSi(CH₃)₂R,are relatively sensitive to water.The more bulky R,R'and R″,the more stable the compound to water.The structures were characterized by elementary analysis,IRand ¹H NMR.
