In examples, these compounds are prepared by (i) introducing the substituent R‹ or R, (ii) converting the compound where R*A is MeO to the corresponding phenol, or (iii) introducing a CN or NO 2 group into the Ph ring represented by R‹. Details are given for the preparation of 2,2<SP>1</SP>-dithienyl iodonium chloride and its substituted analogues. It is stated that certain compounds of the invention have diuretic, saluretic and uricosuic activity. |
