The diol R2C(SiMe2OH)2 (R Me3Si) has been shown to react with: SO2Cl2 to give R2CSiMe2OSO2OSiMe2; SOCl2 to give R2C(SiMe2Cl)2; Me3SiI or Me3SiCl to give R2C(SiMe2OSiMe3)2; R′COCl; (R′ Me or CF3) to give R2C(SiMe2O2CR′)-(SiMe2Cl); (R′CO)2O (R′ Me or CF3 to give R2C(SiMe2O2CR′)2; with MeOH containing acid to give R2C(SiMe2OMe)2; with neutral MeOH to give R2C-(SiMe2OMe)2 and probably R2CSiMe2OSiMe2;
二醇- [R 2 C(森达2 OH)2(R我3 Si)的已被证明与反应:SO 2氯2生成R 2 CSiMe2OSO2OSiMe 2 ; SOCl 2给出R 2 C(SiMe 2 Cl)2;Me 3 SiI或Me 3 SiCl生成R 2 C(SiMe 2 OSiMe 3)2;R'COCl; (R'Me或CF 3)得到R 2 C(SiMe 2 O 2 CR')-(SiMe 2 Cl);(R'CO)2 O(R'Me或CF 3产生R 2 C(SiMe 2 O 2 CR')2;与含酸的MeOH产生R 2 C(SiMe 2 OMe)2;与中性MeOH产生R 2 C- (SiMe 2 OMe)2和可能的R 2 CSiMe2OSiMe 2; MeLi得到R 2 C(SiMe 2 OLi)2(后者与PhMeSiF 2反应得到R 2 CSiMe2OSiMePhOSiMe 2)。二乙酸R 2 C(SiMe
