Abstract
The cyclization reaction kinetics has been studied in methanolic aceta te, N-methylmorfoline and triethylamine buffers at a constans ionic st renght I = 0.1 mol.1(-1). In the acetate buffers cyclization goes thro ugh the dianionic intermediate In-1(2-) only and in the N-methylmorfol ine and triethylamine buffers via the zwitterionic intermediate In-1(/-).
