The effect of silyl groups on other molecular centers of the silylmethyl chlorides XYZSiCH2CI is discussed on the grounds of the data gathered chiefly from literature. The magnetic shielding of the CH2 protons in X3SiCH2 Cl is shown to be in accordance with operation of inductive effect of the X3Si groups. The 3sCI_NQR frequencies are influenced by intramolecular interaction (the DC-effect) and this interaction is disclosed to diminish with ...
