ABSTRACT:
Silanes of the formulain-line-formulae description="In-line Formulae" end="lead"?Ra1R4-a-xSiLx  (I)in-line-formulae description="In-line Formulae" end="tail"?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,R1is an optionally substituted 2-norbornyl radical,L is a leaving group,a is 1, 2 or 3 andx 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.
