The C-13 and H-1 NMR spectra of siloles C4Ph4SiRH (R = Cl, Ph, H, Me, t-Bu)
have been completely assigned using 2D NMR techniques. Values of the coupl
ing constants (1)J(SiX) (X = C, H) were measured. The analysis of the chemi
cal shifts delta (C-ipso) and (1)J(SiH) showed their linear dependence on T
aft's substituent constant.
