Siliconization for Organic Compounds
A key difference between carbon and silicon (and why you usually can't make an all-silicon version of an organic compound where all its carbons are replaced with silicon) is that long chains of silicon atoms are not stable. Another key difference is that a hydrogen attached directly to silicon, as in silane, is typically more reactive--say toward hydrolysis or oxidation--that one attached to a carbon atom. I do not know of any process to directly "silanize" a carbon compound, as stated in your question.
