摘要:A ruthenium-phosphine complex can be used as a catalyst in a method for the catalytic synthesis of urea. The method may comprise more particularly a reaction of formamide or of formamide with ammonia in the presence of the catalyst to form urea and hydrogen. Through the use of the ruthenium-phosphine complex as the catalyst, catalytic preparation of urea from formamide or from formamide with ammonia is provided for the first time. This allows for synthesis under mild conditions and virtually no formation of byproducts. Further, using an acid as a cocatalyst in the catalytic synthesis or the reaction can lead to an improvement in urea yield.

标 题 :Device and methods for directed synthesis of chemical libraries
发明人：BATTERSBY BRONWYN J; MILLER CHRISTOPHER R; TRAU MATHIAS; WAY JEFFERY C; JOHNSTON ANGUS
摘要:The invention features a sort computer which interfaces with a sorting device in order to control the sorting of beads on a bead by bead basis. The invention further features novel methods for the directed synthesis of encoded libraries of oligomers, e.g., oligonucleotides, on beads. These methods allow the synthesis of libraries that are sufficiently large to permit complex genomic analyses to be carried out. New methods of using the encoded libraries also are described.
