- Unanticipated participation of HCl in nucleophilic chlorination reaction: Expedient route to meta chlorophenols
-
o-Quinone monoketals participated in a 1,4-addition reaction with HCl furnishing m-chlorophenols in high yields. Several readily available o-quinone monoketals were selected to display the generality of this serendipitous and unprecedented reaction and the results are presented herein.

- CFBSA: a novel and practical chlorinating reagent
-
A structurally simple, highly reactive chlorinating reagent, N-chloro-N-fluorobenzenesulfonylamine (CFBSA), was conveniently prepared from inexpensive Chloramine B in high yield. A wide range of substrates were chlorinated with it to obtain products in good to high yields and appropriate selectivity.

- Synthesis, X-ray structure determination, and formation of 3,4,5-trichloroquaiacol occuring in kraft pulp spent bleach liquors
-
3,4,5-Trichloroquaiacol, which is formed during bleaching of chemical pulp and shown to bioaccumulate in fish, has been synthesized.The structure of the compound has been determined by means of X-ray analysis.The values of the 13C nmr chemical shifts and melting point differ from those previously reported.A reaction mechanism is suggested for the formation of 3,4,5- and 4,5,6-trichloroguaiacol.
