摘要: Silanes of the formula Ra1R4-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.
