The Effect of Solvent Accessible Surface on Hammett-Type Dependencies of Infinite Dilution 29Si and 13C NMR Shifts in Ring Substituted Silylated Phenols Dissolved in Chloroform and Acetone
Original language description
Infinite dilution 29Si and 13C NMR chemical shifts were determined from concentration dependences in dilute chloroform and acetone solutions of para substituted silylated phenols, 4 R C6H4 O ?SiR'2R'' (R = Me, MeO, H, F, Cl, NMe2, NH2, and CF3) where thesilyl part included groups of different sizes: dimethylsilyl (DMS, R' = Me, R'' = H), trimethylsilyl (TMS, R' = R'' = Me), tert. butyldimethylsilyl (TBDMS, R' = Me, R'' = CMe3) and tert. butyldiphenylsilyl (TBDPS, R' = C6H5, R'' = CMe3). Dependences ofthe silicon and C-1 carbon chemical shifts on Hammett substituent constants are discussed. It is shown that substituent sensitivity of these chemical shifts is reduced by association with chloroform, the reduction being proportional to solvent accessiblesurface of the oxygen atom in the Si-O-C link.
