“…Aliphatic azides could be detected by azide reduction to amine by a phosphine, followed by (or concurrent with) treatment with the Kaiser test reagents . Indeed, the simple addition of triphenylphosphine and water to the standard Kaiser test protocol provided a selective indicator for the presence of azides in solution, on TLC plates, or when supported on resin beads . The tolerance of the azide detection method toward other functional groups is high, being compromised only by fast oxidation of the phosphine or quenching of the generated amine.…”

Colorimetric Tools for Solid-Phase Organic Synthesis

One of the unresolved problems of solid-phase organic synthesis (SPOS) is the availability of general and rapid methods to monitor the transformation of functional groups present in molecules supported on insoluble supports. Color tests, far from providing the ultimate solution, may help in detection (and sometimes in quantification) of different functional groups. In this short review, we have collected most of the methods available and applied in SPOS with an Experimental Section that describes the procedure we have successfully applied to bead analyses in our laboratories.
