A NEW METHOD FOR MONITORING DEDIAZONIATION REACTIONS - SIMULTANEOUS MONITORING OF CONCENTRATION AND RATES OF PRODUCT FORMATION AND LOSS OF STARTING MATERIAL FOR THE DEDIAZONIATION OF P-METHYLBENZENEDIAZONIUM TETRAFLUOROBORATE

We have examined the kinetics and mechanism of the dediazoniation reac tion of p-methylbenzenediazonium tetrafluoroborate in the presence and absence of CuCl2, using a methodology developed by us that allows, si multaneously, and within the same experiment to identify, to quantify, and to obtain the rate constants for the formation of all dediazoniat ion products, and, indirectly, the rate constant for the diazonium sal t decomposition. The methodology developed combines the use of couplin g reactions, to form a stable azo dye, followed by analysis by HPLC. ( C) 1998 John Wiley & Sons, Inc.
