A cross-coupling reaction of diaryl disulfides with substituted 5-chloropyrazole-4-aldehydes has been developed using 10 mol% of copper powder as the catalyst and caesium carbonate as the base, in DMSO at 90°C for 5–15 h under an atmosphere of nitrogen to give a series of new functionalised pyrazole sulfides in good to excellent yields (71–94%).

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
