Abstract:
The diol R2C(SiMe2OH)2 (R = Me3Si) has been shown to react with: SO2Cl2 to give R2
Me2; 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 R2
Me2; MeLi to give R2C(SiMe2OLi)2 (and the latter to react with PhMeSiF2 to give R2
Me2). The diacetate R2C(SiMe2O2CMe)2 reacts with CsF in MeCN to give R2C(SiMe2F)2; it does not react with NaN3 or KSCN in MeCN, but the bis(trifluoroacetate) reacts with these salts with KOCN to give R2C(SiMe2X)2 (X = N3, NCS, NCO).
