The silanol TsiSiMe2OH (Tsi = (Me3Si)3C) has been made by hydrolysis of the iodide TsiSiMe2I in H2O/dioxane or H2O/Me2SO. It has been shown to react with some acid chlorides RCOCl (R=Me, Et, CICH2 Ph, 4-O2NC6H4, and 3,5- (O2N)2C6H3) and anhydrides (RCO)2O (R = Me, CF3, or Ph) to give the carboxylates TsiSiMe2OCOR, and with SO2Cl2 to give TsiSiMe2OSO2Cl. The triol TsiSi(OH)3 has been made by treatment
通过在H 2 O /二恶烷或H 2 O / Me 2 SO中水解碘化物TsiSiMe 2 I来制备硅烷醇TsiSiMe 2 OH(Tsi =(Me 3 Si)3 C)。已证明它可以与某些酰氯RCOCl(R = Me,Et,CICH 2 Ph,4-O 2 NC 6 H 4和3,5-(O 2 N)2 C 6 H 3)和酸酐( RCO)2 O(R = Me,CF 3或Ph)生成羧酸盐TsiSiMe 2 OCOR,并带有SO 2 Cl 2得到TsiSiMe 2 OSO 2 Cl。通过在150°C下用H 2 O / Me 2 SO或AgClO 4水溶液和有机溶剂的混合物处理TsiSiH(OH)I来制备三醇TsiSi(OH)3。已表明三醇与RCOCl(R = Me,Et或Ph)或(RCO)2 O(R = Ph)反应生成相应的TsiSi(OCOR)3,而与(CF 3 CO)2 O生成TsiSi(OH)2(OCOCF
