## Abstract The ^13^C NMR signals for some 2โ€ethylthioโ€, 2โ€ethylsulphinylโ€ and 2โ€ethylsulphonylโ€4โ€ฒโ€substituted acetophenones were assigned. The carbonyl carbons exhibit a progressive upfield shift on going from the ketosulphides to the ketosulphoxides and to the ketosulphones. The ฮฑโ€methylene carbo
