权利人:CUSTOMARRAY INC
摘要:There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.

摘要:In an embodiment, a method of producing a fluoroolefin comprises coupling 3,3-dichloro-1,1,1,2,2-pentafluoropropane (CF3—CF2—CHCl2) in a liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CHâ•?CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises coupling 1,1,1-trichloropentafluoropropane (CF3—CF2—CCl3) in a vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3—CF2—CClâ•?CCl—CF2—CF3). The method may further include forming the CF3—CF2—CCl3 in a vapor phase from CF3CF2CHmCl3-m and chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene with hydrogen (H2) in a vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CHâ•?CHCF2CF3 and 3-chloro-1,1,1,2,2,5,56,6,6-decafluoro-3-hexene (CF3CF2CClâ•?CHCF2CF3).
