The invention relates to novel silane compounds corresponding to the formula (I) below:
A-E-X (I)
in which:
X represents a silyl group capable of creating a covalent bond after reaction with the hydroxyl or hydride functional groups of a support;
E represents an organic spacer group;
A represents a group chosen from the groups of formulae below:
in which:
Z1 to Z5 independently represent a hydrogen atom or a halogen atom;
Z6 and Z7 represent a group for protecting the phosphonic acid functional group, a hydrogen atom or a monovalent cation;
Z8 to Z12 independently represent a group for protecting the carboxylic acid functional group, a hydrogen atom or a monovalent cation; and
Z13 represents an imidazole, N-hydroxysuccinimide, nitrophenyl, pentafluorophenyl or acid anhydride group.
Use of these silane compounds for functionalizing solid supports and for immobilizing biological molecules on these supports.

anhydride additives, the catalyticdecarbonylation of p-nitrophenylesters of aliphatic carboxylic acids to their corresponding olefins, including commodity monomers like styrene and acrylates, has been developed. The reaction is catalyzed by palladiumcomplexes in the absence of added ligands and is promoted by alkali/alkaline-earth metal halides. Combination of catalyticdecarbonylation and Heck-type coupling

Esterification of carboxylic acids capable of forming ketene intermediates upon treatment with carbodiimides permits the selectiveacylation of alcohols in the presence of phenols lacking strong electron-withdrawing groups. The selectivity of acylations involving highly acidic phenols could be reversed through the addition of catalytic amount of acid. Esterification of other carboxylic acids was found
