标 题:Process for the synthesis of carboxamides
发明人：RODEFELD LARS; SEVERINS CHRISTIAN; HAMMERER TIM; TSICHLA ANGELIKI
权利人:BAYER CROPSCIENCE AG
摘要:The invention provides a process for the synthesis of carboxamides, comprising the steps: a) provision of a carboxylic acid ester of the formula RCOOR' and ammonia (NH 3 ), b) mixing of the carboxylic acid ester of the formula RCOOR' and of ammonia (NH 3 ), and c) reaction of the carboxylic acid ester of the formula RCOOR' and of ammonia (NH 3 ) to give a carboxamide of the formula RCONH 2 and R'OH, characterized in that the ammonia in step a) is introduced in liquid form or in supercritical form. The invention further provides a plant for carrying out the process according to the invention.

摘要:The present invention provide several methods of derivatizing a surface of a support with one or more linkers thus providing a suitable platform for synthesis of a polymer array, particular a nucleic acid array. Some methods derivatize a surface with a self-assembled monolayer (SAM) of a linker. The SAM confers advantages of hydrolytic stability, broad compatibility with synthesis and detection chemistries, and reduced emergence of latent functional groups during polymer array synthesis. Substrates can also be derivatized with multi-layers of SAMs providing greater hydrolytic stability. Substrates can also be derivatized by synthesizing a linker in situ on the substrate by atom transfer radical polymerization of functional and functional monomers. Appropriate selection of monomers reduces emergence of latent functional groups in subsequent array synthesis.
