Silanes of the formula R1aR4-a-xSiLx (I) where each R is identical or different and is a monovalent, optionally substituted hydrocarbon radical which is free of aliphatic carbon-carbon multiple bonds and has from 1 to 18 carbon atoms per radical, R1 is an optionally substituted 2-norbornyl radical, L is a leaving group, a is 1, 2 or 3 and x is 1 or 2, with the proviso that the sum of a+x<=4, are useful for protecting functional groups of organic compounds (2) which have at least one functional group having an active hydrogen atom, preferably as a hydroxyl group -OH, a thiol groups -SH, an amine group -NH- or -NH2, a carboxyl group -COOH, or an amide group -CONH- or -CONH2.
