Websymmetrical thioketone 2e, are new compounds. Four of the prepared thioketones 2c–e and i were treated with an equimolar amount of meta-chloroperbenzoic acid (m-CPBA) in CH 2Cl 2 solu-tion at 0°C, and immediate decolorization was observed in all cases. The symmetrical bis-(selenophen-2-yl)thioketone (2i) was converted to In organic chemistry, thioketones (from Ancient Greek θεῖον (theion) 'sulfur'; also known as thiones or thiocarbonyls) are organosulfur compounds related to conventional ketones in which the oxygen has been replaced by a sulfur. Instead of a structure of R2C=O, thioketones have the structure R2C=S, which is reflected by the prefix "thio-" in the name of the functional group. Unhindered al…
