Yes No Iodo version, (CSI2) were prepared by treating thiophosgene , FTIR shows slight change in frequency. When iodo treated with diazo 1a, as expected it give diiodo products 6a. Mass M/z shows 625, which is consistent with molecular formula 618 and on combination with Lithium ion. The carbon peaks of diiodo bearing carbon in NMR data (-7 ppm) is matching with predicted value. This method is addition to literature, where in reported method 6a obtained one out of multiple products . (Scheme-8)
